Solution for cos(x)cos(x)=-cos(x) equation:


Simplifying
cos(x) * cos(x) = -1cos(x)

Multiply cos * x
cosx * cos * x = -1cos(x)

Multiply cosx * cos
c2o2s2x * x = -1cos(x)

Multiply c2o2s2x * x
c2o2s2x2 = -1cos(x)

Multiply cos * x
c2o2s2x2 = -1cosx

Solving
c2o2s2x2 = -1cosx

Solving for variable 'c'.

Reorder the terms:
cosx + c2o2s2x2 = -1cosx + cosx

Combine like terms: -1cosx + cosx = 0
cosx + c2o2s2x2 = 0

Factor out the Greatest Common Factor (GCF), 'cosx'.
cosx(1 + cosx) = 0

Subproblem 1

Set the factor 'cosx' equal to zero and attempt to solve: Simplifying cosx = 0 Solving cosx = 0 Move all terms containing c to the left, all other terms to the right. Simplifying cosx = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 2

Set the factor '(1 + cosx)' equal to zero and attempt to solve: Simplifying 1 + cosx = 0 Solving 1 + cosx = 0 Move all terms containing c to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + cosx = 0 + -1 Combine like terms: 1 + -1 = 0 0 + cosx = 0 + -1 cosx = 0 + -1 Combine like terms: 0 + -1 = -1 cosx = -1 Divide each side by 'osx'. c = -1o-1s-1x-1 Simplifying c = -1o-1s-1x-1

Solution

c = {-1o-1s-1x-1}
