# Laplace transform and differential equations.

Not what you're looking for?

Find the inverse Laplace transform of (s^3+s^2+2/s) / [s^2(s^2+3s+2)]

Using this (or otherwise), Find the solution of the equation y"+3y'+2y = 1-t

Find the transform of the following functions:

f(t) = (1+t^2)[u(t-1)-u(t-2)] where u(t) is the unit step function.

f(t) = sin(t) for 0<t<Pi and f(t)=0 for Pi<t<2*Pi
