F(x)=x-cosx

Solution for F(x)=x-cosx equation:

Simplifying
F(x) = x + -1cosx

Multiply F * x
xF = x + -1cosx

Reorder the terms:
xF = -1cosx + x

Solving
xF = -1cosx + x

Solving for variable 'x'.

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

Add 'cosx' to each side of the equation.
cosx + xF = -1cosx + cosx + x

Combine like terms: -1cosx + cosx = 0
cosx + xF = 0 + x
cosx + xF = x

Add '-1x' to each side of the equation.
cosx + -1x + xF = x + -1x

Combine like terms: x + -1x = 0
cosx + -1x + xF = 0

Factor out the Greatest Common Factor (GCF), 'x'.
x(cos + -1 + 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 '(cos + -1 + F)' equal to zero and attempt to solve:

Simplifying
cos + -1 + F = 0

Reorder the terms:
-1 + F + cos = 0

Solving
-1 + F + cos = 0

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

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

Reorder the terms:
-1 + 1 + F + cos = 0 + 1

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

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

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

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

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

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

Simplifying
0 = 1 + -1F + -1cos
