Match each of the trigonometric expressions below with the equivalent non-trigonometric function from the following list. Enter the appropriate letter (A, B,C, D, or E) in each blank.
A. tan(sin−1(x/4))
B. cos(sin−1(x/4))
C. (1/2)sin(2sin−1(x/4))
D. sin(tan−1(x/4))
E. cos(tan−1(x/4))

Step-by-step explanation:

In each case, draw the right triangle which produces the inverse trig value. That is, label the two sides as needed, and calculate the third side.

It should be clear that

sin(2α) = 2 sinα cosα

So,

See what you can do with the others.
