Simplifying sin(4x) + -1sin(2x) = sin(x) Remove parenthesis around (4x) ins * 4x + -1sin(2x) = sin(x) Reorder the terms for easier multiplication: 4ins * x + -1sin(2x) = sin(x) Multiply ins * x 4insx + -1sin(2x) = sin(x) Remove parenthesis around (2x) 4insx + -1ins * 2x = sin(x) Reorder the terms for easier multiplication: 4insx + -1 * 2ins * x = sin(x) Multiply -1 * 2 4insx + -2ins * x = sin(x) Multiply ins * x 4insx + -2insx = sin(x) Combine like terms: 4insx + -2insx = 2insx 2insx = sin(x) Multiply ins * x 2insx = insx 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 = 1insx 1insx = insx + -1insx Combine like terms: insx + -1insx = 0 1insx = 0 Divide each side by '1'. insx = 0 Simplifying insx = 0 The solution to this equation could not be determined.
