Laplace transformation question

  1. Apr 24, 2015 #1
    Trying to answer the question:
    x"+3x'+2x=u(t-1)+2(t-2)u(t-2), x(0)=1, x'(0)=-1

    My book has the answer but I need to see how to solve a problem like this. Professor didn't have time to cover this section but he said one of these might be on the test. Any help is greatly appreciated.

    Paul's Online Math Notes has a pretty good introduction to Laplace Transforms (and so should the text used in your DE course):

    http://tutorial.math.lamar.edu/Classes/DE/LaplaceIntro.aspx

    There are some lecture videos here:

    Check out Post #10 at the link above. There are 3 or 4 videos which show how to use LTs to solve ODEs for various forcing functions.

    Unfortunately, PF is not set up to be a tutoring service, so after studying the material, if you have any questions, please feel free to post any follow ups.
