## Homework Statement

sin(pi +A) sec(pi-A)

--------- + ---------- = 0

cos (2pi + A) csc(2pi-A)

## Homework Equations

cscx=1/sinx

secx=1/cosx

sin(x+y)=sinxcosy+cosxsiny

sin(x-y)=sinxcosy-cosxsiny

cos(x+y)= cosxcosy-sinxsiny

cos(x-y)= cosxcosy+sinxsiny

## The Attempt at a Solution

**LS**

sin pi cosA + cosA sin pi || 1/cos pi cos A + sin pi sin A

------------------------

**+**--------------------------

cos 2pi cosA + sin 2pi sinA || 1/sin pi cos A - cos pi sin A

the || is a seperator of the fractions

if it helps, i got this one to equal zero :)
