Simplifying -1sin(2x) = sinx Remove parenthesis around (2x) -1ins * 2x = sinx Reorder the terms for easier multiplication: -1 * 2ins * x = sinx Multiply -1 * 2 -2ins * x = sinx Multiply ins * x -2insx = sinx Solving -2insx = insx Solving for variable 'i'. Move all terms containing i to the left, all other terms to the right. Add '-1insx' to each side of the equation. -2insx + -1insx = insx + -1insx Combine like terms: -2insx + -1insx = -3insx -3insx = insx + -1insx Combine like terms: insx + -1insx = 0 -3insx = 0 Divide each side by '-3'. insx = 0 Simplifying insx = 0 The solution to this equation could not be determined.
