If it's not what You are looking for type in the equation solver your own equation and let us solve it.
Simplifying sinx = sin(2x) Remove parenthesis around (2x) insx = ins * 2x Reorder the terms for easier multiplication: insx = 2ins * x Multiply ins * x insx = 2insx Solving insx = 2insx Solving for variable 'i'. Move all terms containing i to the left, all other terms to the right. Add '-2insx' to each side of the equation. insx + -2insx = 2insx + -2insx Combine like terms: insx + -2insx = -1insx -1insx = 2insx + -2insx Combine like terms: 2insx + -2insx = 0 -1insx = 0 Divide each side by '-1'. insx = 0 Simplifying insx = 0 The solution to this equation could not be determined.
