0=ln(cos(2x))

Solution for 0=ln(cos(2x)) equation:

Simplifying
0 = ln(cos(2x))

Remove parenthesis around (2x)
0 = ln(cos * 2x)

Reorder the terms for easier multiplication:
0 = ln(2cos * x)

Multiply cos * x
0 = ln(2cosx)

Remove parenthesis around (2cosx)
0 = ln * 2cosx

Reorder the terms for easier multiplication:
0 = 2ln * cosx

Multiply ln * cosx
0 = 2clnosx

Solving
0 = 2clnosx

Solving for variable 'c'.

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

Add '-2clnosx' to each side of the equation.
0 + -2clnosx = 2clnosx + -2clnosx
Remove the zero:
-2clnosx = 2clnosx + -2clnosx

Combine like terms: 2clnosx + -2clnosx = 0
-2clnosx = 0

Divide each side by '-2'.
clnosx = 0

Simplifying
clnosx = 0
