Professor takes 2 class days to explain this. Meanwhile, youtube takes 7 minutes.

Thank you! I'm taking an online course and the teacher does nothing. The textbook doesn't explain anything either! I was getting so frustrated, this cleared everything up!!

Test on monday been studying all week from my notes in class. I understood this way 10 times better then the way my teacher explained it and it's a lot faster thank you soooo much... my teacher needs to watch your videos and learn how to teach

Well, NOW I know what finding the phase shift really is about; finding where the stuff in the brackets equals zero! Wish my teacher would have just told us that instead of the steps to take with all the conditions...

Excellent explanation on how to solve this type of graphs....I undestood everything and so I can explain to my son who is struggling with this topic....awesome teacher...thanks so much...

Dude, I wish you were my math teacher. In school i have to ask questions but you explain things so thoroughly that I don't have any questions. Thank you, man your videos are really helpful.

Never thought of the phase shift in that way before (the zero thing). This guy's brilliant.

@templar19 13 жыл бұрын

I don't know what it is...but the way he says 'Let's try another one' at 1:30 just makes me feel really excited and confident! And that's saying something...I've been teaching math for 5 years!

@TheSpiralTeselation 12 жыл бұрын

THANK YOU I did NOT get this when my teacher explained it and my book only had the "cute" examples where there never was any phase shift, or the period was a nice even number like pi all the time, and then threw me questions that involved combinations of these things without teaching us how to deal with it. You are awesome.

WoW, all I have learned is that you realy need someone to know how to teach. No teacher should be called "Teacher" if he doesn't know how to make a pupil understand. Your online lessons are like a ray of light...I can understand math much better than before lol.

I tried your method for problem 2 and 3 on problem one and I got a start of -pi/4 and an end of 7pi/4. Why does it not work on the first problem? Is it because the period is one?
