1.) Find an expression equivalent to sec theta sin theta cot theta csc theta.
sec theta ~
2.) Find an expression equivalent to cos theta/sin theta .
cot theta ~
3.) Simplify (tan^2 theta + 1)/(tan^2 theta) .
4.) Use a sum or difference identity to find the exact value of sin 15°.
-(sqrt)2 - (sqrt)6/ 4
(sqrt)6 - (sqrt)2/ 4 ~
(sqrt)6 + (sqrt)2/ 4
(sqrt)2 - (sqrt)6/ 4
5.) Which expression is equivalent to cos (theta – 2pi)?
cos theta ~
the ones with ~ are my answers!
