This resource site is a user-friendly and simple calculator for finding the Laplace Transform of a function that gives the solutions in a very simple way.
Type of Material:
Simulation
Recommended Uses:
Individual practice, in-class demonstrations, homework, group activities.
Technical Requirements:
Any browser.
Identify Major Learning Goals:
The purpose of this site is to assist users in calculating the Laplace Transform of a function. Users can enter any function they want to transform it.
Target Student Population:
College Upper Division
Prerequisite Knowledge or Skills:
Calculus II, Differential Equations
Content Quality
Rating:
Strengths:
The calculator allows users to input the expression for which they want to calculate the Laplace Transform. A brief description of the Laplace transform is included along with and example at the bottom of the page.
Concerns:
The site does contain ads, and the site has a typo (it is mentioned f(x)) while it should be in terms of t which is f(t) for the inserted function. Otherwise, if the user enters the function in terms of x, the answer will be wrong. In addition, random examples option in the site will not give an accurate example.
While the solution is displayed under the heading “Step by step solution”, steps are not actually shown. Step-by-step solutions are not detailed. The calculator does not always display correct solutions to entered expressions.
Potential Effectiveness as a Teaching Tool
Rating:
Strengths:
This could be a nice resource for students wanting to review or check their answers on a homework assignment.
Users may enter the function they want to transform it via the Laplace transform. The site provides a brief explanation of Laplace transform with an example.
Concerns:
No Laplace transform table is provided in the site. The step by step solution is not written in detail with more explanation.
Users can click on the “random examples” button to view the solution to an example problem. However, correct solutions to the “random examples” are not always displayed. As correct solutions are not always displayed, this could be a source of frustration to users.
Ease of Use for Both Students and Faculty
Rating:
Strengths:
The site is very simple to use, and students can use it easily.
This calculator includes instructions and the “calculate” button is clearly highlighted in green.
Concerns:
It would be helpful to have a “mathtype” option for entering expressions.
