Question

How do you prove`(cosx)(cscx)(tanx)=1`?

Answer 1

`(cancel(cosx))(1/cancel(sinx))(cancel(sinx)/cancel(cosx)) =1`

Explanation:

To prove `(cosx)(cscx)(tanx) =1`

Convert everything to `sin` and `cos`

`(cosx)(1/sinx)(sinx/cosx) =1`

Now cancel

`(cancel(cosx))(1/cancel(sinx))(cancel(sinx)/cancel(cosx)) =1`
