Question

Refer to the graph of y = sin x or y = cos x to find the exact values of x in the interval [0, 4π] that satisfy the equation. (Enter your answers as a comma-separated list.)
5 sin x = 5/2

Answer 1

With a little algebra
\[\sin x=\frac{1}{2}\]
so... where on the interval from 0 to 4pi does the sin x = (1/2)?

Answer 2

umm pi/3?

Answer 3

Hint... the arcsin(1/2)= (pi/6)
