this video made this whole amplitude business SO ridiculously easy compared to my book. i swear only people who hate teaching write textbooks. thank you for existing!!

It's summer, I passed Calc II last week thanks to you PatrickJMT, and I'm still watching your videos, haha!!

thanks for the USEFUL comment :) i appreciate it

Congratulations on you passing Calculus. I took 2 years of it plus an additional 300/3000 level calculus. Best choice in my life given that I am an engineer. I still use it even after I last took it 18 years ago. The beautiful language of math, which no one can escape.

its only awesome when you can pass it. last time i liked math was when i was in high school, above 95% each semester for the last 3 years of high school, i loved math, but got in university, everything was moving so fast i didn't have time to enjoy math, it quickly became a chore, which was fine with me but i had a ton of other things to learn. i forgot even the easiest things like this video and had to come here on you tube for a quick refresh.

Thank you so much. I was struggling so much with this until now.

Hi Patrick, I would love to see a graph of that function. If you can, please post it. Thanks for your help. Your videos are very helpful.

This video really helped me with my hw.

How is the phase shift pie? What happens to the pie over 2?

pinkloverevaAnna

you guys its really aint that bad, just needs tons of practice and confidance pretty much everything in life needs these two things and u can do anything!.. but since most of us slack on our duties (including myself) that's what we get bad results.

i don't know, it is working for me

patrickjmt

sir patrick, I wonder if u ever did the second and third derivative and their tests? it would be so helpful to me, thank you :)

I’m still confused, how do I know if the phase shift is going left or right depending on the problem?

Why is the horizontal shift pi and not pi over 2

How do tell what the B value is and why is the 1/2 the B value.

-scieng-

wait wouldn't you have to take -c/b to find the horizontal phase shift? So would it not be -2pi? Or am I missing something?

ValiantNoob

hey patrick. why i can't open your website?

alifsarji

why period must find with 2pie divides by B value i cant understand?

This is way simpler than my math teacher who never ceases to rant on and on

ElusiveMonk

How did you get the phase shift? That's my only problem ππ
