Simplifying Cos(8x) = 2cos2(4x) + -1 Remove parenthesis around (8x) osC * 8x = 2cos2(4x) + -1 Reorder the terms for easier multiplication: 8osC * x = 2cos2(4x) + -1 Multiply osC * x 8osxC = 2cos2(4x) + -1 Remove parenthesis around (4x) 8osxC = 2cos2 * 4x + -1 Reorder the terms for easier multiplication: 8osxC = 2 * 4cos2 * x + -1 Multiply 2 * 4 8osxC = 8cos2 * x + -1 Multiply cos2 * x 8osxC = 8cos2x + -1 Reorder the terms: 8osxC = -1 + 8cos2x Solving 8osxC = -1 + 8cos2x Solving for variable 'o'. Move all terms containing o to the left, all other terms to the right. Add '-8cos2x' to each side of the equation. -8cos2x + 8osxC = -1 + 8cos2x + -8cos2x Combine like terms: 8cos2x + -8cos2x = 0 -8cos2x + 8osxC = -1 + 0 -8cos2x + 8osxC = -1 Reorder the terms: 1 + -8cos2x + 8osxC = -1 + 1 Combine like terms: -1 + 1 = 0 1 + -8cos2x + 8osxC = 0 The solution to this equation could not be determined.
