Simplifying sin2(3x) = sin2(x) Remove parenthesis around (3x) in2s * 3x = sin2(x) Reorder the terms for easier multiplication: 3in2s * x = sin2(x) Multiply in2s * x 3in2sx = sin2(x) Multiply in2s * x 3in2sx = in2sx Solving 3in2sx = in2sx Solving for variable 'i'. Move all terms containing i to the left, all other terms to the right. Add '-1in2sx' to each side of the equation. 3in2sx + -1in2sx = in2sx + -1in2sx Combine like terms: 3in2sx + -1in2sx = 2in2sx 2in2sx = in2sx + -1in2sx Combine like terms: in2sx + -1in2sx = 0 2in2sx = 0 Divide each side by '2'. in2sx = 0 Simplifying in2sx = 0 The solution to this equation could not be determined.
