Question

cot θ ∙ sec θ = csc θ

Answer 1

That's correct. :)

Answer 2

Can you verify the identity ?

Answer 3

Oh yes

Answer 4

It is not hard. You can do it

Answer 5

First, \(cot\theta\) and \(sec\theta\) are equal to what?

Answer 6

As you know, \(cot \theta= \frac{cos\theta}{sin\theta}\) and \(sec\theta=\frac{1}{cos\theta}\). Therefore, \(\frac{cos\theta}{sin\theta} \times \frac{1}{cos\theta} = \frac{1}{sin\theta}=csc\theta\).

Answer 7

Oh thanks :)
