Find all angles between 0° and 180° satisfying the given equation. (Enter your answers as a comma-separated list.) V3 sin() =

Solution

sin is +ve in 1st ans 2nd quadrants

theta in 1st quadrant , theta = pi/3 = 60 degrees

theta in 2 nd qudrant theta = pi=pi/3

                                              =2pi/3 = 120 degrees

sol. are theta = pi/3,2pi/3 = 60, 120
