Question

How to find out if this an identity?
sec x + csc x = 1
Help Please, I have no clue.

Answer 1

you can show that it is not (because it certainly is not) by picking a value for \(x\) and see that what you get does not add up to one

Answer 2

pick something easy, like \(\frac{\pi}{4}\)

Answer 3

them compute
\[\sec(\frac{\pi}{4})+\sin(\frac{\pi}{4})\] and see that you do not get 1
