Is the integral formula equivalent to -P(V2-V1)? can you use both to find -P delta V?

Yes they are the same and I think you can use both interchangeably.

Yes -P(V2-V1 is what you get when you solve

Yep the formulas give the same answer. I think Dr.Lavelle was just using the integral to show how the P delta V formula was derived.

the two equations mean the same thing just written in different ways

Yes, the integral just implies that a very small volume is being changed at every instant therefore it all can be summed up with an integral, while if the change of volume is large and sudden ten delta v can just be used.

The equations are the same, Dr. Lavelle wanted to utilize the integral to derive where P (delta V) came from showing that the sum of a small change in volume is equivalent to the integral.
