Additional Laplace Transform Example; Quiz 4 Update
Posted on May 12, 2005, 7:18pm

I just posted an additional Laplace transform example that shows how to deal with Heaviside and delta functions. Please see the downloads section, as usual.

As for memorizing the Laplace transforms, I'd recommend learning all but the last line:

L( f*g ) = F(s)G(s)

This notation f*g is a convolution, and not a product. Since you're not learning convolutions, ignore this last line.

Lastly, I'll post the Quiz 4 solutions no later than 5:00pm tomorrow. Thanks -- Paul

Laplace Transform Help
Posted on May 3, 2005, 1:27pm

I just posted a handout Laplace transform self-quiz. Please use it as you study Laplace transforms in the coming weeks. Even if you are supplied with a sheet of transforms on your next exam, knowing them will save you a LOT of time and help you to work more quickly in the limited time setting of an exam. -- Paul
