Question

How would you describe the graph of the cosine function.

Answer 1

wavy

Answer 2

Seriously? Value is 1 and slope is 0 at x = 0, value is 0 and slope is 1 at x = pi/2.

Answer 3

Sorry slope is -1 at x = pi/2

Answer 4

you can use the
y=cos(x)
put x=0
u get y=1
put x=90
you get y=0 and so on
its graph is periodic which means it repeats itself after some interval.

Answer 5

And the interval is 2 pi.

Answer 6

And it's closely related to sine.
