Simplifying 3(sin(4x)) = -6(sin(2x)) Remove parenthesis around (4x) 3(ins * 4x) = -6(sin(2x)) Reorder the terms for easier multiplication: 3(4ins * x) = -6(sin(2x)) Multiply ins * x 3(4insx) = -6(sin(2x)) Remove parenthesis around (4insx) 3 * 4insx = -6(sin(2x)) Multiply 3 * 4 12insx = -6(sin(2x)) Remove parenthesis around (2x) 12insx = -6(ins * 2x) Reorder the terms for easier multiplication: 12insx = -6(2ins * x) Multiply ins * x 12insx = -6(2insx) Remove parenthesis around (2insx) 12insx = -6 * 2insx Multiply -6 * 2 12insx = -12insx Solving 12insx = -12insx Solving for variable 'i'. Move all terms containing i to the left, all other terms to the right. Add '12insx' to each side of the equation. 12insx + 12insx = -12insx + 12insx Combine like terms: 12insx + 12insx = 24insx 24insx = -12insx + 12insx Combine like terms: -12insx + 12insx = 0 24insx = 0 Divide each side by '24'. insx = 0 Simplifying insx = 0 The solution to this equation could not be determined.
