Simplifying 2sin(x) + 1 + -1sin(2x) = 0 Multiply ins * x 2insx + 1 + -1sin(2x) = 0 Remove parenthesis around (2x) 2insx + 1 + -1ins * 2x = 0 Reorder the terms for easier multiplication: 2insx + 1 + -1 * 2ins * x = 0 Multiply -1 * 2 2insx + 1 + -2ins * x = 0 Multiply ins * x 2insx + 1 + -2insx = 0 Reorder the terms: 1 + 2insx + -2insx = 0 Combine like terms: 2insx + -2insx = 0 1 + 0 = 0 1 = 0 Solving 1 = 0 Couldn't find a variable to solve for. This equation is invalid, the left and right sides are not equal, therefore there is no solution.
