The Graph of Cosine, y = cos (x)

[Serotonii]

Thank you so much. My teacher moves so fast and I am NOT an auditory learner when it comes to math. You are a relief and explain things so well.

"alright, whatever" hahahahahahahahaha. such a cool guy

I'm in Pre-calc/Trig and some things I don't get even when the teacher explains them, So I gave up on her and the lessons she leads me to and I come to you. You explain things so easily for me, and I'm so grateful to have found you. I understand these things so much quicker when I watch your videos! I usually go to Khanacademy too but I'm like NOPE Patrick got me! :D

@antonio0076 maybe you can help that cute girl in math class next time : )

[MaruiJunkie]

I would like to thank you for clearing my problem with some of the material on my Trig Exam next week. You sir have another subscriber!!!

[birusarkar]

my teacher actually made us watch this for precalc class

[dpasingh]

Thank you dear Patrick for your crystal clear like explanation. actually your explanation has removed all my doubts regarding plotting the trigonometric graphs. Thank you very much once again....

[Killahertz]

that really helped me, thanks dude, I'm going to watch more of your videos

[lolagomez]

Thank you so much for this I understand my homework for precalc now. I will totally recommend you with my classmates.

[shadowgirl]

Thank you so much. I'm in an online course and the textbook uses the method you were describing in your video, but they made the concept far too difficult. I think they were diving more into the theory than I was able to understand, but now I can understand what they're asking of me.

@sarazuu
If you're working in radians, yes it does. If you're in degrees, pi/2 = 90 deg, and cos90= 0.

[NUBeTuBer]

dude you are an excellent tutor!!!! Thank You So Much

[MarketerMilk]

You explained this a thousand times better than my pre cal teacher! Thank you so much!

[gracetate]

Thank you!!!! I completely understand now!

[patrickjmt]

@filmcruiser88 if you did not see trig much stuff in calculus, then your calculus class sucked a big one

[nbrunojunior]

This video of yours helped me tremendously. Thanks.

[FuerzaImperialOficial]

you make it look simple as hell! My teacher makes it to complicating.

if you guys have trouble for math, its sometimes the way you study. check out a book called "a mind for numbers" the way to study math is two study for 30 minutes really hard, no distractions what so ever, take a 5-10 min break, keep doing this for two hours. then leave the math and go do somthing where you dont have to think. like nap, gym, watch tv, take a walk, play with your dog... just for a few hours then come back to the math. it will help.. it works..
