Simplifying -4sin(2x) + 4cos2(2x) = 0 Remove parenthesis around (2x) -4ins * 2x + 4cos2(2x) = 0 Reorder the terms for easier multiplication: -4 * 2ins * x + 4cos2(2x) = 0 Multiply -4 * 2 -8ins * x + 4cos2(2x) = 0 Multiply ins * x -8insx + 4cos2(2x) = 0 Remove parenthesis around (2x) -8insx + 4cos2 * 2x = 0 Reorder the terms for easier multiplication: -8insx + 4 * 2cos2 * x = 0 Multiply 4 * 2 -8insx + 8cos2 * x = 0 Multiply cos2 * x -8insx + 8cos2x = 0 Reorder the terms: 8cos2x + -8insx = 0 Solving 8cos2x + -8insx = 0 Solving for variable 'c'. Move all terms containing c to the left, all other terms to the right. Add '8insx' to each side of the equation. 8cos2x + -8insx + 8insx = 0 + 8insx Combine like terms: -8insx + 8insx = 0 8cos2x + 0 = 0 + 8insx 8cos2x = 0 + 8insx Remove the zero: 8cos2x = 8insx Divide each side by '8os2x'. c = ino-1s-1 Simplifying c = ino-1s-1
