Use the Quadratic Formula to solve the equation in the interval [0, 2π). Then use a graphing utility to approximate the angle x. (Enter your answers as a comma-separated list. Round each answer to four decimal places.)
12 sin^2 x − 13 sin x + 3 = 0
solve for sin(x) using quadratic formula:
sin%28x%29+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
a=12, b=-13, c=3
ans:
sin(x)=3/4, 1/3
x=0.8481,2.2953,0.3398,2.8018
