Question

Simplify with math and/or identities. The equation is: cot(-B)sec(-B)sin(-B) So far I have -cot B sec B -sin B.

Answer 1

cotB=(cosB/sinB)
secB=(1/cosB)
use these to arrive at your answer

Answer 2

\[\cot(-B) = - \cot(B)\]
\[\sec(-B) = \sec(B)\]
\[\sin(-B) = - \sin(B)\]

And then use :

\[\cot(B) = \frac{\cos(B)}{\sin(B)}\]
\[\sec(B) = \frac{1}{\cos(B)}\]

After then, just simplify, cancel whatever is being cancelled...
