Solution for F(x)=3cos(x*8) equation: 


Simplifying
F(x) = 3cos(x * 8)

Multiply F * x
xF = 3cos(x * 8)

Reorder the terms for easier multiplication:
xF = 3cos(8x)

Remove parenthesis around (8x)
xF = 3cos * 8x

Reorder the terms for easier multiplication:
xF = 3 * 8cos * x

Multiply 3 * 8
xF = 24cos * x

Multiply cos * x
xF = 24cosx

Solving
xF = 24cosx

Solving for variable 'x'.

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

Add '-24cosx' to each side of the equation.
-24cosx + xF = 24cosx + -24cosx

Combine like terms: 24cosx + -24cosx = 0
-24cosx + xF = 0

Factor out the Greatest Common Factor (GCF), 'x'.
x(-24cos + 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 '(-24cos + F)' equal to zero and attempt to solve:

Simplifying
-24cos + F = 0

Reorder the terms:
F + -24cos = 0

Solving
F + -24cos = 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 + -24cos = 0 + -1F

Combine like terms: F + -1F = 0
0 + -24cos = 0 + -1F
-24cos = 0 + -1F
Remove the zero:
-24cos = -1F

Add '24cos' to each side of the equation.
-24cos + 24cos = -1F + 24cos

Combine like terms: -24cos + 24cos = 0
0 = -1F + 24cos

Simplifying
0 = -1F + 24cos
