Establish the identity. secant squared theta (1 minus sine squared theta )equals1 rewrite the left side expression by expanding the product. secant squared theta minus secant squared theta sine squared theta (do not simplify.) apply the appropriate quotient identity and/or the appropriate reciprocal identity to the expression in the previous step. secant squared theta minus (nothing )sine squared theta multiply and apply the appropriate quotient identity to the expression from the previous step. secant squared theta minus nothing the expression from the previous step then simplifies to 1 using what?

a. reciprocal identity
b. quotient identity
c. cancellation property
d. even-odd identity
e. pythagorean identity
