What are natural logarithms and their properties
Вставка
- Опубліковано 17 вер 2013
- 👉 Learn all about the properties of logarithms. The logarithm of a number say a to the base of another number say b is a number say n which when raised as a power of b gives a. (i.e. log [base b] (a) = n means that b^n = a). The logarithm of a negative number is not defined. (i.e. it is not possible to find the logarithm of a negative number). There are some properties of logarithm which are helpful in simplifying and evaluating logarithm problems. Knowledge of these properties is a valuable tool in solving logarithm problems.

I'm re-learning this for University. Pay attention now guys, you'll save lots of time in the future.
Most of the material is so boring, no matter how well you may understand it 25 minutes before a test, a couple of years later there is no way you will still have the abilities to do the calculations
Relearning in AP Calculus B/C for some rough derivative problems lmao wish I learned this back in Algebra 2 or whenever I was supposed to
What’s funny is I learned this already last year mostly from these videos. And forgot all of it. Coming back to the same place cause it’s the only way I live found that makes it make sense. Ik im gonna forget it again though. You only remember what you use commonly.
@@lynxrbeam8732 that or what you understand deeply.
Agreed
God damn Marissa
viveck sachdev stupid Marissa
Watching this in 2020 and Marissa is still chatting in the background
she was a problem fr
lol....watching this in 2021, and Marissa is still chatting in the background!!!
@@wesleydonovan4262 LOL yup to this day
isn’t it kind of sad that we need to watch youtube videos about what we need to be able to do in school because of how badly we actually learn things in school itself
Not really.
@@joshhhh___ schools should at least be able to teach the curriculum they test kids on, so yes, it is sad
@Joe fair enough but like I read a lot of comments from others who kept saying they needed to know it for school but they weren’t taught it properly
Yeah, it would be nice if they were at least as good as UA-camrs at teaching.
But then again, not all people will be able to learn the same thing from the same teaching technique, so how could the teacher teach this so 100% of all students learnt it?
No you just don’t concentrate enough, like me lol
This clarified more than an entire lesson at school in 4 minutes, THANK YOU!
This dude right here saves my butt every time lol
I have geophysics degree and I watch these videos to remind myself from time to time. This guy does a good job explaining it. Marissa is prob going to do FINE ARTS.
Yeah! Marissa!
Hi
Hello
4th year nuclear engineering here: Thanks man, we use it so much sometime we forget what it really means.
Same for me. 4 years of Mathematics and only 2 years later I forgot almost everything. Just shows how incredibly inefficient learning is without applying anything ever.
@@ThefamousMrcroissant lol, if you are studying fucking math, then when the hell am i going to use this bs for my finance major?
To calculate compound interest
Amazing. Thanks for the clear and easy explanation!
you are very welcome!
Be glad that they teach this stuff in high school. In my country, we never saw this stuff due to our collapsing education department. As an engineering student having to learn calculus without this stuff I can say that these videos are a ton of help
So happy to be able to help you out?!’
@brianmclogan In our textbook, its just log x and not ln x there is just a single line in the textbook(which like no one reads) which says that log (base e)x is equals to log x in further exercises and thats it. None of my classmates dont even know whats e or its value or properties.
@@brianmcloganPowers of two…A viable shortcut…
Anyone here learning this for high-school 😂
Yeah course but we don’t call it high school it’s sixth form
anyone relearning this for college cause they forgot it from high school
@@liamels6282 I'm in college and I don't even remember if I learn it in highschool or not
I don't even know what it is
Meeee
I'm relearning it
This man is a very good teacher. Explains principles very clearly and understandably. Thank you!
woman
He teaches it as if you already understand all of the principles and procedures. That isn't teaching; that's reviewing.
*m a r i s s a n o i s e s*
Systems engineering major, you help so much.
Yep, electrical engineering student here. 🙂
Wow. Perfect explanation. For some reason I completely miss natural logs in learning math throught years and now I have them at university. Videos like this make our lifes easier.
These kids don't understand how good a teacher they have
Thank you for an awesome explanation!! I really learned a lot!
simple, informative and rather fun way of teaching. wished you were my calc teacher!
Omt thank you sooo much, I needed to understand natural logs for biology, and we haven’t gotten to that in my math classes!
Computing and IT major, you just saved my life man
Excellent, Brian McLogan and Keep It Up, You Were Doin’ Very Well! ✨
best prof ever!!! no capping
Bohot acha laga sir ye session dekhkar.. Me Vidya Guru ke sessions se bhi kafi kuch seekha hai.. Unke teachers exam relevant important questions kafi easy methods se karwate hain.
wow what a fantastic explanation it was very confusing and annoying topic but now its easy thank you sooooooo much
You made it look simple and understandable
Great !!
you've fixed my YEARS of misunderstanding in less than 5 minutes.
Right Mr August Luna
thanks for making this concept clear for me!
You are a great teacher. Thank you, Brian.
This Video was Of Great Help!
Thank You So Much:D
Electrical Engineer Student studying for degree here and this helps a lot thanks!
it all means hardwork and patience, stretched over an year atleast, it is beautiful presentation.
Thank you, It was very beneficial, I learnt alot!!
My professor in college has all his lectures online, but certain concepts just don't click for me how he explains them. You make it make sense though, and I appreciate that
You are
Very welcome!!
@@brianmclogan Yh I think you are a great teacher
Thank you !
I have been learning a new things.
That's awesome 🤩
We’ll done. I am helping my College daughter with this and this was very clear. 🙏🏾
you are an absolute saint
Awesome!!
That sigh at the end. Classic. Good job man.
I've always had a very painful mental block with logarithms. Right now I'm learning about the Binary Cross Entropy activation function for GANs (generative adversarial neural nets (used in Google Inception)). This was a simple review of natural log. Thanks.
I think the kids probably don't understand that the less you're using math in your life, the worse and more mundane your job is going to be. At that age, they don't get it. If you're a dreamer, eventually you're going to go hard core math.
You’re the best teacher ever
You always make math easier for me 😍♥️
صح 🌚
this man is a lifesaver
Thank you sir!
Thank you sir!!
Now I can understand questions easily.....thank you once again
Suupeerrbb sir..😍😍
THANK YOU SO MUCH, just saved my life
happy to be able to help
thank you this helped immensely
Thank u so much u help me greatly 👍🏿
Understand logarithms with a fraction - ua-cam.com/video/msvn-pJ9Bs0/v-deo.html
Nice sir . thank u so much.
Thanks a lot :)
Was explaining 2 my friend how lock picking in Bethesda games is like the bisection method search algorithm with a time complexity of ln(n) where n is the size of the list you're searching and remembered oh wait its log base 2 becuz you cut the list in half with each operation and realized i don't remember what natural log even is and then i was like.. i think its base e but wut is e? Suffice to say this video did not answer my question but sure did take me back and this guy seems like a pretty good teacher, MARISSA
Thank You Sir
Love From India❤️
Marissa pay attention sis
Helped a lot
Thank you sir
I wish I could take one of your classes online!
thank you!
I love this man
Thank you, sir
thank you senpai
you are very welcome!
Automation engineering major here, Thank you so much.
3:57(has all the answer to the Ln equations+we can see how why the Ln equations have the answers they have)
I don't know if this is meant to be part of a bigger course, but this video can be much better if it explains why one would ever want to know what "ln X" is.
The only case I know of is if you're doing statistical research and you have populations from huge countries in your data. Then instead of saying that the population is 50.000.000, you just instead say "ln (50.000.000)" and write whatever that number is instead.
Supposedly it makes it easier to see percentual changes in the population when the population grows exponentially, but I've no idea how that works. All I see is that the number "50.000.000" suddenly is "17.7" and "6.000.000" becomes "15.6".
@@davecullins1606 Ahhh.... kind of like the Richter Scale concept...
Brian McLogan looks like Randy Orton. Not understanding him for whole video feels like RKO!
Exactly
great sir good and easy learning .i like it thanks sir
I've been wondering how does ln work for the longest time. Thanks!
Thank you 😭😭😭😭
Thank you ❤️
you are very welcome!
this man is the freaking goat
Marissa gettin called out here kekw
Fun fact, natural logs were discovered before "e", some time later Euler determined that the base of the natural logs was "e"
love from india ......... very nicely explain
Thanks a lot please uploaded lecture on msc math
Thank you for the wonderful explanation.
I would only argue that ln(x)=ln(y) is not the same as ln(e^x) = ln(e^y)
Its very nice am so happy just continue wow i said wow wow wow
MashahAllah thanks sir g.
I think its only Y = X but not necessarily also equal to lnX and lnY
Right,
I was searching for comments who noticed it.
I think is not so much that we need to learn it in school ( as we do) it’s all involve in the time that it requires to practice and understand the concepts, half of the answers in everything in math , it’s understanding what we are reading.
However Videos it’s just a form of investing the time into what we need to learn . As if we were or had more time in class to practice.
Tutoring it’s always available for free at school most of the time.
Thank you for your opinion.
I've been studying political science for almost 4.5 years now. I've always procrastinated on finding out what they were because they seemed so complex when just looking at them, but turns out they're easy AF!
@Laura McDowell Would never have stayed for as long as I have if I didn't. The learning system at uni is really bogging every education down, so the love for your profession is what drives most people through it.
thanks sir
Nice!!!
Love you infinity from Bangladesh 🙂🇧🇩🔥
Very good
Thank you for your service Brian! BTW no offense but dude you kinda look like Billy Corgan lol
This video solved one of my biggest problem
awesome!
know it sounds silly but i never got this- THANK YOU
Thanks
If i get accepted in CPP i'll donate 100$ to you and The Organic Chemistry Tutor, wish me luck
Well, how did that go?
@@yoshima7654 Haha thanks for reminding me!! I got in!! It is the most competitive scholarship program in my country and i got accepted with my first choice major, i’m very thankful for youtube it played a major role in helping me get accepted! ❤️😂
I wonder how Marissa's handling life, not paying attention in class
Love from India 🇮🇳
Good work sir .u have remove my dought.
its doubt not dought
these students are so lucky ;-;
Wow i actually understand it easily it's not hard
I actually saw someone talking about in() in yt andi didn't know what does that mean but it turn out to be simple
I have question tho i have a calculator and i discovered that e is const number that is ≈2.72
That's correct right?
The natural log 1, (an exponent of e), plus the natural log 2 (an exponent of e) equals the natural log sum of 3 (an exponent of e)
How would one write the above summation in ln form?
Thanks, Mr McLogan! You made me understand this like it was a piece of cake. Perfect!
PS: I am actually in 9th grade, no kidding, NGL!
Im learning this in preparation of sixth form and im super confused... all i know is tat u can use In() to find the power of x from "mind your decisions" yt channel; his questions
Shout out to teachers that teach from basics up and don’t expect you do know the blanks they decide to leave our based off assumption!
So true
