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