Question

Cosx + Sinx
Secx cscx

Answer 1

If those are fractions, then:
\[\frac{ cosx }{ secx }+\frac{ sinx }{ cosecx } = \frac{ cosx }{ (\frac{ 1 }{ cosx }) }+\frac{ sinx }{ (\frac{ 1 }{ sinx }) } = \cos^2x + \sin^2x = 1\]

Answer 2

oh, ok. you multiply the tops and the flip of the bottom and then add
