Answer to Problem 105AYU

The identities established.

Explanation of Solution

Given information:

Write a few paragraphs outlining your strategy for establishing identities.

Calculation:

Consider the steps which used in this exercise to establishing various identities.

See the complicated side of identities, and then try to use different algebraic formula, trigonometric identities, and then write an expression in terms of sine and cosine.

Take the common factor out, and then apply the multiplication and division to get the appropriate expression to the known formula by using common subtraction and addition,

Hence finally we got the proved identity.

Hence, the identities established.
