Solution for sin(2x)cosx-cos(2x)sinx=sinx equation:


Simplifying
sin(2x) * cosx + -1cos(2x) * sinx = sinx

Remove parenthesis around (2x)
ins * 2x * cosx + -1cos(2x) * sinx = sinx

Reorder the terms for easier multiplication:
2ins * x * cosx + -1cos(2x) * sinx = sinx

Multiply ins * x
2insx * cosx + -1cos(2x) * sinx = sinx

Multiply insx * cosx
2cinos2x2 + -1cos(2x) * sinx = sinx

Remove parenthesis around (2x)
2cinos2x2 + -1cos * 2x * sinx = sinx

Reorder the terms for easier multiplication:
2cinos2x2 + -1 * 2cos * x * insx = sinx

Multiply -1 * 2
2cinos2x2 + -2cos * x * insx = sinx

Multiply cos * x
2cinos2x2 + -2cosx * insx = sinx

Multiply cosx * insx
2cinos2x2 + -2cinos2x2 = sinx

Combine like terms: 2cinos2x2 + -2cinos2x2 = 0
0 = sinx

Solving
0 = 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.
0 + -1insx = insx + -1insx
Remove the zero:
-1insx = insx + -1insx

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

Divide each side by '-1'.
insx = 0

Simplifying
insx = 0

The solution to this equation could not be determined.
