Solution for sin(2x)*cos(x)=cos(2x)*sin(x) equation: 


Simplifying
sin(2x) * cos(x) = cos(2x) * sin(x)

Remove parenthesis around (2x)
ins * 2x * cos(x) = cos(2x) * sin(x)

Reorder the terms for easier multiplication:
2ins * x * cos * x = cos(2x) * sin(x)

Multiply ins * x
2insx * cos * x = cos(2x) * sin(x)

Multiply insx * cos
2cinos2x * x = cos(2x) * sin(x)

Multiply cinos2x * x
2cinos2x2 = cos(2x) * sin(x)

Remove parenthesis around (2x)
2cinos2x2 = cos * 2x * sin(x)

Reorder the terms for easier multiplication:
2cinos2x2 = 2cos * x * ins * x

Multiply cos * x
2cinos2x2 = 2cosx * ins * x

Multiply cosx * ins
2cinos2x2 = 2cinos2x * x

Multiply cinos2x * x
2cinos2x2 = 2cinos2x2

Add '-2cinos2x2' to each side of the equation.
2cinos2x2 + -2cinos2x2 = 2cinos2x2 + -2cinos2x2

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

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