I'm in a rutt for a tutorial question:

The question is basically to show that the work done during a reversible adiabatic expansion of an ideal gas is

W = (P1V1 – P2V2)/(1 ‐ γ) ........ Y is gamma

2. Relevant equations

3. The attempt at a solution

I've got so far as to get W= (P1V1^γ – P2V2^γ)

due to P1V1^γ being constant for a reversible adiabat

also that W= -PdV

But i havent a clue how to get the 1-Y at the bottom, me thinks its intergrating for V to get this but my maths is very bad so i dont know how to do this.
