Question

Find four solutions of the equation
(sinx)^2=1/4 for x between 0 and 360 degrees.

Answer 1

Taking the square root of boths sides of equal sign. \[\sin x = +/- 1/2\]
x=30 degrees, 150 degrees, 210 degrees, and 330 degrees.

Answer 2

how did you find x to =30 degrees?

Answer 3

Take the inverse sin of 1/2 (.5) and get 30 degrees then go around the circle and the rest become obvious.
