Establish the identity tec theta sin 0 tan theta Write the

Establish the identity, tec theta sin 0 = tan theta Write the left side in terms of sine and cosine. sin theta Write the result from the previous step as a single factiveon. (Do not simplify.) The factiveon from the previous step then simplifies to tan 0 using what?

Solution

In the 1st empty box we will write 1/cos theta   , because   sec theta = 1/cos
theta.
it means c option
in the second box we will write sin theta/costheta= tan theta by using quotient identity
