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