Ease of Use:

Overview:: This page contains a symbolic calculator that computes the Fourier transform or Laplace transform of a function entered by the user.. The tool also finds the inverse transforms.
Type of Material:: Simulation
Recommended Uses:: Individual: This can be used by the individual student to check their work and see examples.
Technical Requirements:: Any browser that accepts JavaScript.
Identify Major Learning Goals:: Finding the inverse or direct Fourier or Laplace Transform.
Target Student Population:: Differential Equation or Real Analysis course students.
Prerequisite Knowledge or Skills:: Understanding of what a Fourier Transform and a Laplace Transform are.

Rating:
Strengths:: This site asks the user to enter in a function to transform as a Fourier or Laplace transform directly or as an inverse and then after the user hits the “Compute” button it gives the solution.
Concerns:: It does not have any explanation of the concepts nor does it have any links to explanations. It just gives the answer. Also, it does not specify the domains where the obtained transforms are defined.

Rating:
Strengths:: This site can be used to quickly show students the Fourier or Laplace transform of a function, so that they do not have to go through the difficult calculus to arrive at the answer. It can be used as a calculator that will get them through this part of the question without having to spend most of their time on calculations. The calculator could also serve as a replacement for a basic Laplace (or Fourier) transform table that is used in a course of Differential Equations.
Concerns:: Without accompanying materials, there is no way for students to get additional information to help them understand how the calculations were made or what the concepts are.

Rating:
Strengths:: Since the user only has to type in the function and then select what type of transformation they want done, it is clear what they need to do.
Concerns:: There is no help button or explanation on how to enter in the equation.
