Question

When graphing what happens to the graph due to the -x in this trigonometric transformation:

Answer 1

\[y=\frac{1}{2} \cos (-x- \frac{\pi}{2})\]

Answer 2

Could someone walk me through the process on how I would graph this function?

Answer 3

The period is 2pi correct? Because B is 1, right?

Answer 4

cos(-theta) = cos(theta)

and cos(x+pi/2) = -sin(x)

that divided by 2.

period=pi
