Solution for Sinx=-2cosx*sinx equation: 


Simplifying
Sinx = -2cosx * sinx

Multiply cosx * insx
inxS = -2cinos2x2

Solving
inxS = -2cinos2x2

Solving for variable 'i'.

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

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

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

Factor out the Greatest Common Factor (GCF), 'inx'.
inx(2cos2x + S) = 0


Subproblem 1
Set the factor 'inx' equal to zero and attempt to solve:

Subproblem 2
Set the factor '(2cos2x + S)' equal to zero and attempt to solve:

Simplifying
2cos2x + S = 0

Reorder the terms:
S + 2cos2x = 0

Solving
S + 2cos2x = 0

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

Add '-1S' to each side of the equation.
S + -1S + 2cos2x = 0 + -1S

Combine like terms: S + -1S = 0
0 + 2cos2x = 0 + -1S
2cos2x = 0 + -1S
Remove the zero:
2cos2x = -1S

Add '-2cos2x' to each side of the equation.
2cos2x + -2cos2x = -1S + -2cos2x

Combine like terms: 2cos2x + -2cos2x = 0
0 = -1S + -2cos2x

Simplifying
0 = -1S + -2cos2x

The solution to this equation could not be determined.
