Write the expression in terms of sine and cosine, and then simplify so that no quotients appear in the final expression. sec beta - cos beta. a.1-cos^2beta b. sin^2beta c. cos^2beta d.1 e. sin beta tan beta

E

Step-by-step explanation:

The expression given is:  sec β - cos β ( i will write "beta" instead of the symbol β)

We know that

Substituting this into the the expression and doing some algebra manipulation, we have:

Using the identity   (also ), we can now write:

We know , substituting this, we have:

Answer choice E is the right answer.

what? that isnt a question
