Question

Use basic identities to simplify the expression.

cot θ sec θ sin θ

Answer 1

tan2θ right?

Answer 2

cot A can be written as cos A/ sin A
and sec A can be written as 1/cos A
now try to simplify it...see what cancels...a
and no answer is 1

Answer 3

1 yup

Answer 4

\[\cot \theta= \frac{ 1 }{ \tan \theta }...\frac{ 1 }{ \tan \theta }* \frac{ 1 }{ \cos \theta }* \sin \theta= \frac{ \tan \theta }{ \tan \theta }\]
