Verify that each equation is an identity (1 - sin^(2)((x)/(2)))/(1+sin^(2)((x)/(2 )))= (1+cosx)/(3-cosX)

Given that we have;

By the application of the law of indices and algebraic process of adding a and subtracting a fraction from a whole number, we have;

Step-by-step explanation:

An identity is a valid or true equation for all variable values

The given equation is presented as follows;

From trigonometric identities, we have;

to rewrite a literal equation you may need to divide by a number, or by a variable.
