HELP
for a particular angle, the cosine function f(x)= a cos b(theta) has the following values within one function of the cycle

Answer 1

You should graph it out, just make the points and see if you can connect the dots to form a cosine wave.

Answer 2

im not too sure how i would even begin to graph this

Answer 3

Well let's pick a random point, f(pi/2)=-4 So just graph the point (pi/2,-4) on a graph. Just mark that point up there and see if you can do them all.
