Solution for Cos(x)=Cos(2x)*Cos(3x) equation:


Simplifying
Cos(x) = Cos(2x) * Cos(3x)

Multiply osC * x
osxC = Cos(2x) * Cos(3x)

Remove parenthesis around (2x)
osxC = osC * 2x * Cos(3x)

Remove parenthesis around (3x)
osxC = osC * 2x * osC * 3x

Reorder the terms for easier multiplication:
osxC = 2 * 3osC * x * osC * x

Multiply 2 * 3
osxC = 6osC * x * osC * x

Multiply osC * x
osxC = 6osxC * osC * x

Multiply osxC * osC
osxC = 6o2s2xC2 * x

Multiply o2s2xC2 * x
osxC = 6o2s2x2C2

Solving
osxC = 6o2s2x2C2

Solving for variable 'o'.

Combine like terms: 6o2s2x2C2 + -6o2s2x2C2 = 0
osxC + -6o2s2x2C2 = 0

Factor out the Greatest Common Factor (GCF), 'osxC'.
osxC(1 + -6osxC) = 0

Subproblem 1

Set the factor 'osxC' equal to zero and attempt to solve: Simplifying osxC = 0 Solving osxC = 0 Move all terms containing o to the left, all other terms to the right. Simplifying osxC = 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 + -6osxC)' equal to zero and attempt to solve: Simplifying 1 + -6osxC = 0 Solving 1 + -6osxC = 0 Move all terms containing o to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + -6osxC = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -6osxC = 0 + -1 -6osxC = 0 + -1 Combine like terms: 0 + -1 = -1 -6osxC = -1 Divide each side by '-6sxC'. o = 0.1666666667s-1x-1C-1 Simplifying o = 0.1666666667s-1x-1C-1

Solution

o = {0.1666666667s-1x-1C-1}
