Solution for Sin^3x=sinx equation: 


Simplifying
Sin3x = sinx

Solving
in3xS = 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 + in3xS = insx + -1insx

Combine like terms: insx + -1insx = 0
-1insx + in3xS = 0

Factor out the Greatest Common Factor (GCF), 'inx'.
inx(-1s + n2S) = 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 + n2S)' equal to zero and attempt to solve:

Simplifying
-1s + n2S = 0

Reorder the terms:
n2S + -1s = 0

Solving
n2S + -1s = 0

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

Add '-1n2S' to each side of the equation.
n2S + -1n2S + -1s = 0 + -1n2S

Combine like terms: n2S + -1n2S = 0
0 + -1s = 0 + -1n2S
-1s = 0 + -1n2S
Remove the zero:
-1s = -1n2S

Add 's' to each side of the equation.
-1s + s = -1n2S + s

Combine like terms: -1s + s = 0
0 = -1n2S + s

Simplifying
0 = -1n2S + s

The solution to this equation could not be determined.

This subproblem is being ignored because a solution could not be determined.
