How to solve for x in trigonometric equations
WebTo solve the equation, we begin by rewriting it so that sin x is isolated on the left side. So, first add 1 to each side and then divide each side by 2 . 2 sin x = 1 sin x = 1 2. Since sin x has a period of 2 π , first we find all the solutions in the interval [ 0, 2 π] . The solutions are x = π 6 and x = 5 π 6 .
