Question

Verify the identity

Answer 1

cot θ ∙ sec θ = csc θ

Answer 2

\[\cot \theta=\cos \theta/\sin\]
\[\sec \theta=1/\cos\]

Answer 3

\[(\cos \theta/\sin \theta)(1/\cos \theta)=1\sin\]

Answer 4

opps = \[1/\sin\]

Answer 5

\[1/\sin \theta=\csc \theta \]

Answer 6

So

cotθ=cosθ/sin
secθ=1/cos
(cosθ/sinθ)(1/cosθ)=1/sin
1/sinθ=cscθ

?

Answer 7

yes

Answer 8

Ah ok, got it. thanks

Answer 9

no problem
