Math has always being my top favorite subject, but I have a math teacher that does not teaches and explains well and gets irritated very easily. She even make me to start hate math, but I am now able to have the precious feeling when I understand something in math, and it is all thanks to you. There are no words to describe my gratitude for making this videos 100% free because I will probably be failing my Pre-Calculus class. For me you are my math teacher, you rock! :)
You have no idea how much easier you make my life. Thank you so much!! I watch your videos every time i do my homework, even if i know what i am doing, you always seem to make it more and more clear. God bless you..
dude, i actualy am starting to get this stuff. I sat in class for 2 weeks and don't get almost everything. I come home and watch your video and learn something. I dont think ive had a better teacher than you, i mean i can actually pay attention!!!!!!!! And for me thats a big accomplishment.
HONESTLY you have no idea how much you help me, my night school teacher RUSHES through things and sometimes even misses teaching us the fundamentals but i never freak out, i just zone out and look up your videos later lol you always have the topics i'm looking for and you answer any questions i have THAAAAAAAAAANNNKNK YOOOOOOUUUUUUU!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Thank you for posting this! I had forgotten how to do this so I watched this to review for finals. It was much easier to understand your teaching than what our teacher provided us with!
I have seven letters for you, PatrickJMT--A-M-A-Z-I-N-G!!! You just helped me get unstuck. I've been working on this subject matter for two hours and couldn't figure it out. After watching watching your video, however, I was enlightened. You took a very burden off my back. THANK YOU!!! You are a life saver! :)
Your videos are perfect. My major requires some math classes I really didn't want to take, but now I can just watch your videos the morning of the test and pass them easily! I've barely paid attention all semester and I still have one of the highest grades in the class thanks to you!
How many people watch these videos every time you do your homework?? I know i do, even if i know what i am doing you make me feel more confident with math, for that i could not thank you enough!! Your amazing Patrick keep it up!
@finalshineag thanks! although i am not a professor (that is an earned title by teaching at a university!). let me know what else you want to see... i have lots of calc 2 stuff at this point, but let me know what is missing
@dereboll789 no, i figure they are in any textbook. they are not too terrible to derive, if you want some practice! i am sure you could find the justification with a google search as well
seriously, you're amazing. my teacher handed us hw without even teaching us any of this and i had totally forgotten how to do it! love love love your videos. thanks!
this was super helpful ! my teacher doesnt sufficienly explain how to do problems in class, and we're forced to look elsewhere...thank u soo much for putting up these video's and saving my pre calc grade :D
thank you for doing these videos. i got an excellent grade in prealgebra, and now working with college algebra. thank you so much for helping us with a difficult subject. glad you are doing it. i'd be lost otherwise!
Well, I left my notebook home for a take home assignment. I waited to today to do it (we left school dec 21st, it is now jan 5th) so I'm very grateful for your video!
I just thought i should tell you that your a boss! i have a math test tomorow and i only understood like half the stuff, but thanks to you i might just pass algebra 2. Muchas Gracias amigo!
I can't remember ever doing logarithms in high-school (the teacher would start from Ch. 2 and by the end of the year, we'll be at just chapter 12.5 and the log, sin, tan, cos amd functions would be in the next few chapters. Your a great teacher,any subject in Math I have problems with, I always end up watching your videos
btw the first question or example (2 LN x = 1) u gave i am not understanding the step in which u go (e ^log e X = e^1/2) can u only raise it by e with cancellation or using the Base term of the logarithm?
That was a bit confusing, I'm listening at work as I can't watch it nonstop. Your words said "e to the e is e" but you wrote "e to the e is x". Keeps me on my toes! Thanks for the videos.
I have a question: you talk about the variable e, is that supposed to be italicized? It's hard to explain but my teacher talked about this special variable e, which stands for a number. I don't have very many details because the reason I'm watching vids on this is I don't reallyunderstand it. Do you have a video on this? the special variables (as I call them) e and LN? thank you!
you explain everything so . . . well. idk how to explain it. but, on the part where you used the quadratic formula, could you explain more how you made the sign positive after substituting negative e? i dont understand how you did that without it effecting the 2.
Once again, this is really great! I had to refresh my mind on logs again. You may not be a professor(reading other comments), but are you a teacher? You teach it so simply. Because teachers can teach, not professors, their not technical certified teachers. My professor is foreign, so i dont know what he says most the time :/ Thanks Again though!
@patrickJMT i think what DangerousPirate means is that you're wasting paper when the permanent marker bleeds through to the next sheet. if you put a piece of cardboard under the piece of paper you are using, it can bleed onto that and not onto the next sheet of paper, therefore saving paper.
I just want to add a comment about the answer for the last problem. The answer you wrote down is only half right. Although the quadratic equation does give us a plus or minus solution, only the plus is used because a negative answer is undefined for a ln equation Hope this helps anyone reading... Also, amazing videos. You are literally my second professor. Is there a way to buy your videos for DL or DVD? I can use these videos at school on a portable DVD player
Thanks patrickJMT. What if you have an equation such as... 3 + ln(x) = e^(2x)? Or what about the form x^x = n; or similarly, x*ln(x) = n? I've played around with this and, from what I could dig up (my teachers were of no use), it is solved by what is called a "product log" or the Lambert W function. I'm only in Calculus 2, but I'm very interested in how that style of problem is solved. Is it a brute-force "squeeze theorem" type approach? I know it can't be done algebraically.
well, that isn't done easily by hand, supposedly you have access to a graph calculator which can solve that value for you. You can also use it to estimate the value by reading it off a graph where y = 10^x and check it for x = 2
Hey ur videos are so helpful, just wanted to ask you if you could do a video on solving logarithms equations but with different bases, i don't understand this only part of logarithms, Thanks Cheers
Hello! you're videos are very helpful. However, I am not able to solve this log equation: ln(1/3^1/4)=x. Since the x is already out I guess I cannot use any of the cancellation laws. I really don't know how to do it. Can you please help?
You're always there when I need you. Thank you.
Sincerely,
A Struggling Algebra Student

I really appreciate what you're doing for us! I've been on your channel all day studying for a test on Monday. I appreciate it!
the way you write is so satisfying

I've been watching these videos to help me study for my precalc exam. you make things seem so much easier than my precalc teacher did. thank you
the value of having a teacher you can rewind is unbelievable
@finalshineag thanks! although i am not a professor (that is an earned title by teaching at a university!). let me know what else you want to see... i have lots of calc 2 stuff at this point, but let me know what is missing
@dereboll789 no, i figure they are in any textbook. they are not too terrible to derive, if you want some practice! i am sure you could find the justification with a google search as well
@DangerousPirate my table is fine and this is not a waste of paper. it is probably one of the most useful uses a piece of paper can have.
wait could u simplify the log so like
2ln(x)=1
>ln(x^2)=1
e^1=x^2
x=sqrt(e)
or am i just making it more complicated
I love this guy. 4 hour math classes twice a week...I learn nothing. 10 minutes here and I'm Einstein
seriously, you're amazing. my teacher handed us hw without even teaching us any of this and i had totally forgotten how to do it! love love love your videos. thanks!
this was super helpful ! my teacher doesnt sufficienly explain how to do problems in class, and we're forced to look elsewhere...thank u soo much for putting up these video's and saving my pre calc grade :D
You know what I am at the end of 98 math and not one time has my book or the damn teacher showed me this method. My God people. Thank you patrickJMT..
thank you for doing these videos. i got an excellent grade in prealgebra, and now working with college algebra. thank you so much for helping us with a difficult subject. glad you are doing it. i'd be lost otherwise!
Dude you're a gift from the sky fr
@liverbird66 What sound does a tree make if you hit it with a drumstick? A logarithm.
math takes time! it is a tricky subject; glad i could help you a bit though!
Well, I left my notebook home for a take home assignment. I waited to today to do it (we left school dec 21st, it is now jan 5th) so I'm very grateful for your video!
doooooh, i can not believe i did that. i put some annotations in just now pointing out the mistake. thanks for bringing it to my attention.
@patrickJMT the reason y u r such a good teacher is because u r not jst a mathematician ur a philosopher !
@ilovemysunshine09 yes, i rarely got stuff the first time around!
I just thought i should tell you that your a boss! i have a math test tomorow and i only understood like half the stuff, but thanks to you i might just pass algebra 2. Muchas Gracias amigo!
Thanks for being very cool and teaching out of your own time! You Rock!
In the last example we must reject the negative solution. Great job!
@archerb88 n + 9 = 4n, and check your solutions
Thank you, you have helped me immensely in pre calc
Thankyou...you helped me through the whole semester of college algebra :)
A good 1000 degrees can be partially attributed to you. Thank you for such clear and concise tutorials
you are very welcome!
Thanks for showing the second property!!! My school textbook didn't show the second one.
These videos have helped me so much, it's ridiculous! Thank you!
I can't remember ever doing logarithms in high-school (the teacher would start from Ch. 2 and by the end of the year, we'll be at just chapter 12.5 and the log, sin, tan, cos amd functions would be in the next few chapters.

can u only raise it by e with cancellation or using the Base term of the logarithm?
Thanks so much! I just started Precal but I was needing to brush up on my Algebra II stuff.
for the very beginning, does the base and the "bigger a" have to be equal? if not, which is becomming the base?
@THomasSnipes1181 glad that the videos are helping : )
u are my favorite teacher on UA-cam :)
Thank you! These videos are amazing... they help so much! Keep it up!
Love your videos they help
More then my professor does! Thanks (:
How do you know you have arrived at the answer? Like whether you need to expand or simplify any further.
this is amazing. i should have watched this vid before i took my log test. you rule.
thanks! glad the videos helped :)
That was a bit confusing, I'm listening at work as I can't watch it nonstop. Your words said "e to the e is e" but you wrote "e to the e is x".
Keeps me on my toes! Thanks for the videos.
@DangerousPirate an economist would say "cost of paper
I have a question:
you talk about the variable e, is that supposed to be italicized? It's hard to explain but my teacher talked about this special variable e, which stands for a number.

@Negronigganigga i do what i can. thanks for the kind words.
no problem! glad it helps : )
AHHHHHH.....THANK YOU SO MUCH SIR!!!!!

i love u patrick. u r the best teacher in the world.
@pianoplayindrummer33 thank ya : )

I learn more from you than my math professor. hahahahaha :) still he's a good professor.
i truly do appreciate your help thanks!!
great video..what's missing is the connection between inverse functions and natural log functions..please update if u have time. thanks
can you show us how the mantissa of such number computed i wonder how it had arranged in the table . . . . . thankyou
Thanks sir a lot particularly on that indication of negative sign in logs.
Thanks alot for all your lessons.
This is going to help me in my upcoming higher mathematics test.
i hope you're getting paid for this because you definitely deserve it
well, that isn't done easily by hand, supposedly you have access to a graph calculator which can solve that value for you. You can also use it to estimate the value by reading it off a graph where
y = 10^x and check it for x = 2
good job! This damn test is all about memorizing these rules!
could explain the properties also? proof or just a little info on how it derived. for example, how is a^log(base a)x=x? the second cancellation law.
You are very very brilliant!!! Thanks for detailed explanation.
Thanks man, these are great examples.
@filthsauce yes, i think it really is a good method of learning material - your own 'personal' teacher
Ok so why did u divide both sides by two ? in the 1st example.?
You teach how my Algebra I teacher taught. By example. I find it to be the most effective method.
@archnoriega just doin' what i can
@PatrickAndHisLSD yes, but where is my lsd? i did just buy a san pedro cactus... now just gotta wait for it to grow bigger!
Hey ur videos are so helpful, just wanted to ask you if you could do a video on solving logarithms equations but with different bases, i don't understand this only part of logarithms, Thanks
Cheers
OMG PatJMT YOUR MY BEST MATH TUTOR Ever :D Its like i can understand what youre saying not like my teacher -_-
When do you know to use e or log of e?
ty, but i dont understand why did u divide by 2? can you do that? i thought you cant and you had to raise the 2 as a power so Lnx^2 = 1. Ty
what if for example there was a Constant infront of e? ex; (2e^3x-5=7) would that change anything?
yeah. that's my problem too.
i mean, that is like saying a = b , but b is not equal to a.
lol nice drawing at the end, and these vids are great!
does log how many logs base 2 to make 8 is 4 and ln 4 is the e to the base 2?
so it would be wrong to factor out the ln, and have ln(2x+1+x)?
that's what I did at 6:05. smh
Hello! you're videos are very helpful. However, I am not able to solve this log equation:
ln(1/3^1/4)=x. Since the x is already out I guess I cannot use any of the cancellation laws. I really don't know how to do it. Can you please help?
For the last problem I got x equals e/3. because I square rooted the 2 numbers with power of 2....is that wrong?
Awesome thanks for the help!!! ur an invaluable teacher!!!
@zxBOYERxz i hope the test went well
wait, in the first problem why dont you take the number 2 and turn it into an exponent? to make it ln x square= 1
excellent! tell a friend or two about my wonderfully helpful vids!!! : )
why was the solution for the first example √e?
nice vids, i never learned that you could just set both sides as powers of e. i wonder why?
My math teacher sucks....wish i had you....explains a lot to me thanks
