SOLUTION: Verify that each equation is an identity. {{{cos(alpha-beta)/cos(alpha)sin(beta)}}} = tan(alpha)+cot(beta)

Question 675437: Verify that each equation is an identity.
= tan(alpha)+cot(beta)

Since the arguments on the right side are just and , I'm going to use the cos(A-B) formula on the numerator of the left side so that all the arguments are or :

Since the right side has two terms I'm going to split the fraction on the left into two terms:

Each of the new fractions will reduce:

The first fraction is cot and the second is tan:

Since addition is commutative we can change the order:
