Why do you use laplace transform?

The most generalized reason would be: "To solve initial-valued differential equations of the 2nd (or higher) order." Laplace is a little powerful for 1st order, but it will solve them as well.

Using laplace transform find function y given 2nd derivative of y plus y equals 0 with both initial conditions equal to 0?

Solve y+y=0 using Laplace. Umm y=0, 0+0=0, 0.o Oh well here it is. First you take the Laplace of each term, so . . . L(y'')+L(y)=L(0) Using your Laplace table you know the Laplace of all these terms s 2 L(y)-sy(0)-y'(0) + L(y) = 0 Since both initial conditions are 0 this simplifies to. (MORE)

What is a drawback of trying to solve a partial differential equation explicitly?

As far as I'm aware a PDE can't be solved explicitly because of the nature of the equation. However, you can separate the variables of a PDE essentially turning it into multiple ODEs which then can be solved explicitly. The draw back of this is that most terms in a PDE are a combination of va (MORE)
