How do you do this one? I can't figure it out!
(2 - 5cot x) / (2 + 5cos x) = (2sin x - 5cos x) / (2sin x + 5cos x)
(2 - 5cot x) / (2 + 5cos x) = (2sin x - 5cos x) / (2sin x + 5cos x)

Trigonometric identities are equations that involve trigonometric functions and are always true, regardless of the value of the variable.
Solving trig identities helps simplify complex trigonometric expressions and make them easier to work with in mathematical calculations.
Some common trig identities include Pythagorean identities, double angle identities, and sum and difference identities.
There are several methods for solving trig identities, including using algebraic manipulations, substitution, and converting to equivalent forms. Practicing and memorizing common identities can also be helpful.
Trig identities can have multiple solutions because some trigonometric functions are periodic, meaning they repeat their values in a specific interval. This can result in multiple solutions that satisfy the identity.
