What are the prerequisites for differential equations?
This is a textbook targeted for a one semester first course on differential equations, aimed at engineering students. Prerequisite for the course is the basic calculus sequence. Find the Laplace transform of 3 + t5 + sin(πt). Find the Laplace transform of a + bt + ct2 for some constants a, b, and c.
Can a differential equation be solved without a Laplace transform?
The examples in this section are restricted to differential equations that could be solved without using Laplace transform. The advantage of starting out with this type of differential equation is that the work tends to be not as involved and we can always check our answers if we wish to.
How do you solve a differential equation involving Dirac delta functions?
We work a couple of examples of solving differential equations involving Dirac Delta functions and unlike problems with Heaviside functions our only real option for this kind of differential equation is to use Laplace transforms. We also give a nice relationship between Heaviside and Dirac Delta functions.
