Sorry to be so off topic but does any of you know of a tool to log back into an Instagram account..? I stupidly forgot the login password. I love any help you can offer me
@Xavier Andres Thanks for your reply. I got to the site on google and im waiting for the hacking stuff atm. Takes quite some time so I will reply here later when my account password hopefully is recovered.
It truly amazes me how great channels like this are more helpful than the thousand dollar classes I pay for at university. Thank you so much for these videos!
a 12 minute video from you had me understanding the entire lesson my teacher took 30 minutes to teach. you are single handedly saving my grades for my finals! thank you
I'm in Germany and I have a math test of these graphs next week, but before your video I was very disappointed to get a high score, your videos boosted my confidence and now I can solve math practice questions. Thank you sooooooo muchhhhhh❤❤
I finished college algebra with not really understanding where the sine and cosine wave graph came from until now. Now in calculus, I'm needing to understand where they came from and this cleared the path to comprehension. Thank you!
Thank you so much for this video 🙏 I was crying and stressed out after seeing my teacher twice for help, but you’ve helped me understand in less than 5 min! Thank you so much again😁
Thank you so much for your clear, organized, and well explained videos. It's so hard to find something that explains more complex math in a simpler way, but you manage to do it really well. This video helped so much with an upcoming test, so thank you!!
they gave me a long reading to learn about this stuff and my attention span isnt that great. Everytime I read I zone out. This video clarified a whole lesson for me. Thank you.
Thank you very much, this is one of the best videos that I have watched about Sin and Cos, Could you please explain a little bit deeper about the transformation of the graph, I mean with more examples? Thanks again!
I have this line of code for a MCU and it creates a sine in the Arduino Serial monitor: sine[i] = 2047 + round(2047 * sin(i * PI / 180)); The array contains 360 frames, the height of the "graph" is 4096. How does this work?
I understand the graph and amplitude, P.S., V.S., midline, everything except how to divide the radian fraction pi/2 into 4 pieces. I'm good with fractions so I dunno what the heck im doing. How did you get pi/8, 2pi/8, 3pi/8, 4pi/8? can someone break that down for me? >___
Just multiply by 1/4 to the period and that will give you your scale...so once you get pi/8 then you can multiply that by 2 to get the next one and multiply pi/8 by 3 to get the next one etc. hope that helps!
For y=3cos(1/3)x the period is 6pi. The 1/3 is a horizontal stretch of the graph by a factor of 3. Since the period is 2pi for the parent function the new period will then be 3 times that. Hope that helps.
I have a question, if there was for example y=sin2x. Do we flip the 2 to make it 1/2 and then multiply it by all original sin x coordinates and then graph them?
. Thank you for integrating the unit circle into graphing the parent functions. Can you please explain (at minute 8) why the phase shift is not 90 degrees? Does the 0.5 b value not distribute over x and pi?
Good question...no the .5 doesn’t affect the phase shift. If the problem was y=2sin(4x-pi) then you would want to factor out the 4 from the 4x and the pi and it would look like y=2sin4(x-pi/4) and the phase shift would be right pi/4. Hope that helps you!
My teacher puts a question on the board, doesn’t explain it, and after 5 minutes of nobody moving their pencils she draws the answer without explaining how she did it and moves on.

@Devin Amari instablaster ;)
@Xavier Andres Thanks for your reply. I got to the site on google and im waiting for the hacking stuff atm.

@Xavier Andres It did the trick and I finally got access to my account again. Im so happy:D
Thank you so much you saved my ass !
@Devin Amari glad I could help =)

man this is more like high school stuff tho.
@@tokyo7671 They revise highschool stuff in college .
Those are free level classes that they are allowed to charge whatever they want for
@@tokyo7671 nothing wrong with learning especially at different levels plus that person is likely reviewing which youre supposed to do
I've been learning this for days and I watched one 10 minute video and now it makes sense. The simplistic explanations are always the best
bro same haha

Glad I could help!
Your tutorials are short, simple and most of all rich with information. Thanks saving my grades since start of semester two
Glad you like my short and to the point math tutorials! And I’m glad they are helping you!
this guy taught me more in 10 minutes than my teacher has in 3 days
You sir are the onlyyyy reason I am passing Precalc :)
I finished college algebra with not really understanding where the sine and cosine wave graph came from until now. Now in calculus, I'm needing to understand where they came from and this cleared the path to comprehension. Thank you!
Thank you I liked how you take this subject and explain it so simply my teacher over explains and confused me.. Thanks again your video really helped
Your welcome! Glad my video helped you!
@@MariosMathTutoring I just want to know have you done a video on graphing cosecant, secant, cotangent
I've watched a lot of videos but have never seen your suggestion of "Graphing in Steps". That sir is KEY! Thank you!
Thank you so much for this video 🙏 I was crying and stressed out after seeing my teacher twice for help, but you’ve helped me understand in less than 5 min! Thank you so much again😁
Thank you for your videos! They’re really helping during quarantine 😊
Glad they are helping you during this time Mia!
Thank you so so much for making these. You are a hero who helped me who does badly at math get actually decent grades. Thank you once again
Thank you so much for your clear, organized, and well explained videos. It's so hard to find something that explains more complex math in a simpler way, but you manage to do it really well. This video helped so much with an upcoming test, so thank you!!
Your very welcome! I’m glad my videos are helping you! That’s my goal! Thanks for letting me know and thanks for being part of the channel!
thank you so much! hours over this subject in school didn't get me anywhere but a 10-minute video did!
God bless your heart for explaining something that apparently even professors in University can't do properly.
My exam is in 7 hours. Thank you! You’re a little saver.
You showed this in a way to look at this that was way more intuitive than my university. Thank you!
Thank You so much for teaching me this. I had plenty of trouble trying to understand how to graph any of this.
they gave me a long reading to learn about this stuff and my attention span isnt that great. Everytime I read I zone out. This video clarified a whole lesson for me. Thank you.
You’re welcome!
so clear Sir.I like this video and more than.Thanks
You helped me so much thank you for being so thorough and clear
You’re welcome! Glad you liked the video!
Thank you so much! This video extremely simplifying these 2 kind of graphs! Master🤧
Awesome videos, super helpful 😊
So glad!
OH MY GOSH I have been struggling with this forever! Thank you!!!

You make it easier.
Thanks for explaining it very well sir.. it helps me a lot
You’re welcome Jan!
You so great teacher for me
Very nice video. Thank you so much
thumbs up ! Thanks!
Amazing. Very well explained!
beautifully explained. ty
dude is so clutch
Thank you

I have this line of code for a MCU and it creates a sine in the Arduino Serial monitor: sine[i] = 2047 + round(2047 * sin(i * PI / 180));
The array contains 360 frames, the height of the "graph" is 4096.
How does this work?
thank you so much daddy
Mario is my big daddy as well 🤤
Thank you. Very helpful
You’re welcome Zulfizar!
Great Lesson
MisterQMath glad you liked it
This is literally chapter 5.1 to 5.5 in 12 minutes bet. My test is tomorrow.
yes you saved my life!!
Glad my video helped you Skye!
thanks mario
I understand the graph and amplitude, P.S., V.S., midline, everything except how to divide the radian fraction pi/2 into 4 pieces. I'm good with fractions so I dunno what the heck im doing. How did you get pi/8, 2pi/8, 3pi/8, 4pi/8? can someone break that down for me? >___
Just multiply by 1/4 to the period and that will give you your scale...so once you get pi/8 then you can multiply that by 2 to get the next one and multiply pi/8 by 3 to get the next one etc. hope that helps!
2019 and still helping :D
Yes indeed Edmund! Thanks for noticing! Glad my channel is helping you!
You're the best man!
Thank you this was very helpful also the fact that you started with degrees before useing radians de confused me.
Glad my video helped you David!
I FINALLY GET IT. Thank you so much
Glad my video helped you Arlene!
Thanks
You’re welcome Tadesse!
In y=3cos(1/3x), why is there a 3pi/(1/3) instead of a 2pi/(1/3) for the period formula?
For y=3cos(1/3)x the period is 6pi. The 1/3 is a horizontal stretch of the graph by a factor of 3. Since the period is 2pi for the parent function the new period will then be 3 times that. Hope that helps.
@@MariosMathTutoring Thanks much appreciated
Oh wait, I commented on the wrong video, I meant to comment on the Organic Chemistry Tutor’s video…whoops
I have a question, if there was for example y=sin2x. Do we flip the 2 to make it 1/2 and then multiply it by all original sin x coordinates and then graph them?
period= 2pi/b=2pi/2= pi, which means that one cycle of the graph starts at x=0 and ends at x=pi and the increments of 1/4 period=1/4(pi)= pi/4
Thank you, very Informative.
You’re welcome Arkadios!
. Thank you for integrating the unit circle into graphing the parent functions. Can you please explain (at minute 8) why the phase shift is not 90 degrees? Does the 0.5 b value not distribute over x and pi?

I am now looking at y = cos⅓(6x +π) + 4. Will that be the same as y = cos2(x +π/6) + 4?
Yes
How did you get the answer π/2 in p=2π/4?
You say the minus has the opposite affect. But why? Do we just accept these things like robots or question them?
So what is the answer to my question please?
This video will explain it for you: ua-cam.com/video/no59KJhndfc/v-deo.html
i love u
In what grade is this topic taught in schools? I’m learning it in ninth grade
JY it depends. Usually taught in algebra 2 or Trigonometry, or college algebra.
Sir, do you have any videos on how to solve word problems using sine function
My teacher puts a question on the board, doesn’t explain it, and after 5 minutes of nobody moving their pencils she draws the answer without explaining how she did it and moves on.
Wow.
I wish you taught my math classes.
Thanks! I’m glad my channel is helping you.
I guess you forgot the distributive property.
In degree plsss
8:22 no value for 4 pi, its 2?
7:58 ah
ill be ur rachel and u can be my ross
You look exactly like my math teacher, yet he explains it so bad tbh
Well I hope my videos were able to help you Jan....
