In a mathematical model, a gas is under a pressure of the form P=e-v2 (v is volume). Find the work (in Joules) done on the gas as its volume decreases from infinity to zero.

Use the definition for work.

dW = PdV

Integrate both sides.
 
W = -fnInt(e^v^2, v, infinity, 0)

Seems like just need to set up that definite integral.

Integrate both sides.

W=∫v1v2PdV

∴W=∫0∞PdV

Would he just simply substitute his P in this formula?
