Question

what is the period of the function
y = 2 cos pi x
please help me

Answer 1

can you graph it?

Answer 2

I would but it doesn't give me a graph

Answer 3

can you graph it yourself

Answer 4

ill try my best!

Answer 5

kk good

Answer 6

Given:

y = 2 cos pi x

compare this to the general form

y = a cos bx

Through this comparison you can see that a=2 and b=Pi.

Given the value of b, the period of the cosine function is simply \[\frac{ 2\pi }{ b }\] Plese calculate the period of your function, based upon this info.

Answer 7

It'd be a good idea to actually graph this function AFTER you know the period. You'll be asked again and again in the future to draw trig functions.

Answer 8

thank you I figured it out
