Solution for Cos(3x-10)=cos(5x-40) equation:


Simplifying
Cos(3x + -10) = cos(5x + -40)

Reorder the terms:
osC(-10 + 3x) = cos(5x + -40)
(-10 * osC + 3x * osC) = cos(5x + -40)
(-10osC + 3osxC) = cos(5x + -40)

Reorder the terms:
-10osC + 3osxC = cos(-40 + 5x)
-10osC + 3osxC = (-40 * cos + 5x * cos)
-10osC + 3osxC = (-40cos + 5cosx)

Solving
-10osC + 3osxC = -40cos + 5cosx

Solving for variable 'o'.

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

Add '40cos' to each side of the equation.
-10osC + 40cos + 3osxC = -40cos + 40cos + 5cosx

Reorder the terms:
40cos + -10osC + 3osxC = -40cos + 40cos + 5cosx

Combine like terms: -40cos + 40cos = 0
40cos + -10osC + 3osxC = 0 + 5cosx
40cos + -10osC + 3osxC = 5cosx

Add '-5cosx' to each side of the equation.
40cos + -10osC + -5cosx + 3osxC = 5cosx + -5cosx

Reorder the terms:
40cos + -5cosx + -10osC + 3osxC = 5cosx + -5cosx
