Question

Simplify the expression using the reciprocal relations.
1. cos theta sec theta tan theta

a. sin theta b. 1 c. 0 d. tan theta e. cos theta

Answer 1

\[\cos \theta \times \sec \theta \times \tan \theta\]
\[\sec \theta=\frac{1}{\cos \theta}\]
Can you find the answer by substituting the reciprocal relation for sec theta?

Answer 2

No, im not sure how to do that.

Answer 3

\[\frac{\cos \theta \times \tan \theta}{\cos \theta}=?\]

Answer 4
