Solution for F(x)=cos(sen(2x)) equation: 


Simplifying
F(x) = cos(sen(2x))

Multiply F * x
xF = cos(sen(2x))

Remove parenthesis around (2x)
xF = cos(ens * 2x)

Reorder the terms for easier multiplication:
xF = cos(2ens * x)

Multiply ens * x
xF = cos(2ensx)

Remove parenthesis around (2ensx)
xF = cos * 2ensx

Reorder the terms for easier multiplication:
xF = 2cos * ensx

Multiply cos * ensx
xF = 2cenos2x

Solving
xF = 2cenos2x

Solving for variable 'x'.

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

Add '-2cenos2x' to each side of the equation.
-2cenos2x + xF = 2cenos2x + -2cenos2x

Combine like terms: 2cenos2x + -2cenos2x = 0
-2cenos2x + xF = 0

Factor out the Greatest Common Factor (GCF), 'x'.
x(-2cenos2 + F) = 0


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

Simplifying
x = 0

Solving
x = 0

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

Simplifying
x = 0

Subproblem 2
Set the factor '(-2cenos2 + F)' equal to zero and attempt to solve:

Simplifying
-2cenos2 + F = 0

Reorder the terms:
F + -2cenos2 = 0

Solving
F + -2cenos2 = 0

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

Add '-1F' to each side of the equation.
F + -1F + -2cenos2 = 0 + -1F

Combine like terms: F + -1F = 0
0 + -2cenos2 = 0 + -1F
-2cenos2 = 0 + -1F
Remove the zero:
-2cenos2 = -1F

Add '2cenos2' to each side of the equation.
-2cenos2 + 2cenos2 = -1F + 2cenos2

Combine like terms: -2cenos2 + 2cenos2 = 0
0 = -1F + 2cenos2

Simplifying
0 = -1F + 2cenos2
