Question

What is the domain of validity for cos(θ)csc(θ)=cot(θ)?

Answer 1

\[\dfrac{\cos\theta}{\sin\theta} = \dfrac{1}{\tan\theta}\]\[\Rightarrow \dfrac{\sin\theta}{\cos\theta} = \tan\theta\]Seems familiar, eh?

Answer 2

Yes

Answer 3

When is \(\frac{\sin\theta}{\cos\theta} = \tan\theta\) true?

Answer 4

Im not sure

Answer 5

Uh...

Answer 6

Do you know what \(\frac{\sin\theta}{\cos\theta}\) is?

Answer 7

Oh, it is true, but im nit sure what you mean by "when".
