Simplifying -2sin(x) + -4sin(2x) = 0 Multiply ins * x -2insx + -4sin(2x) = 0 Remove parenthesis around (2x) -2insx + -4ins * 2x = 0 Reorder the terms for easier multiplication: -2insx + -4 * 2ins * x = 0 Multiply -4 * 2 -2insx + -8ins * x = 0 Multiply ins * x -2insx + -8insx = 0 Combine like terms: -2insx + -8insx = -10insx -10insx = 0 Solving -10insx = 0 Solving for variable 'i'. Move all terms containing i to the left, all other terms to the right. Divide each side by '-10'. insx = 0.0 Simplifying insx = 0.0 The solution to this equation could not be determined.
