Solution for Sin(2x)=sinx equation:


Simplifying
Sin(2x) = sinx

Remove parenthesis around (2x)
inS * 2x = sinx

Reorder the terms for easier multiplication:
2inS * x = sinx

Multiply inS * x
2inxS = sinx

Solving
2inxS = insx

Solving for variable 'i'.

Move all terms containing i to the left, all other terms to the right.

Add '-1insx' to each side of the equation.
-1insx + 2inxS = insx + -1insx

Combine like terms: insx + -1insx = 0
-1insx + 2inxS = 0

Factor out the Greatest Common Factor (GCF), 'inx'.
inx(-1s + 2S) = 0

Subproblem 1

Set the factor 'inx' equal to zero and attempt to solve: Simplifying inx = 0 Solving inx = 0 Move all terms containing i to the left, all other terms to the right. Simplifying inx = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 2

Set the factor '(-1s + 2S)' equal to zero and attempt to solve: Simplifying -1s + 2S = 0 Reorder the terms: 2S + -1s = 0 Solving 2S + -1s = 0 Move all terms containing i to the left, all other terms to the right. Add '-2S' to each side of the equation. 2S + -2S + -1s = 0 + -2S Combine like terms: 2S + -2S = 0 0 + -1s = 0 + -2S -1s = 0 + -2S Remove the zero: -1s = -2S Add 's' to each side of the equation. -1s + s = -2S + s Combine like terms: -1s + s = 0 0 = -2S + s Simplifying 0 = -2S + s The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
