Solution for Sin*3x=sinx equation:


Simplifying
Sin * 3x = sinx

Reorder the terms for easier multiplication:
3inS * x = sinx

Multiply inS * x
3inxS = sinx

Solving
3inxS = 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 + 3inxS = insx + -1insx

Combine like terms: insx + -1insx = 0
-1insx + 3inxS = 0

Factor out the Greatest Common Factor (GCF), 'inx'.
inx(-1s + 3S) = 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 + 3S)' equal to zero and attempt to solve: Simplifying -1s + 3S = 0 Reorder the terms: 3S + -1s = 0 Solving 3S + -1s = 0 Move all terms containing i to the left, all other terms to the right. Add '-3S' to each side of the equation. 3S + -3S + -1s = 0 + -3S Combine like terms: 3S + -3S = 0 0 + -1s = 0 + -3S -1s = 0 + -3S Remove the zero: -1s = -3S Add 's' to each side of the equation. -1s + s = -3S + s Combine like terms: -1s + s = 0 0 = -3S + s Simplifying 0 = -3S + 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.
