This site contains a free onine calculator that will find the Wronskian of the set of functions, with steps shown. Supports up to 5 functions, 2x2, 3x3, etc.
Type of Material:
Simulation
Recommended Uses:
This site would be useful for in-class demonstrations, group activities, assignments, and individual student practice.
Technical Requirements:
Any browser
Identify Major Learning Goals:
The major goal of this site is to provide guidance in calculating the Wronskian (and, hence, determining linear dependence/independence) of a set of functions.
Target Student Population:
Differential Equations students
Prerequisite Knowledge or Skills:
Calculus I. Calculus II, Linear Algebra
Content Quality
Rating:
Strengths:
This site allows users to calculate the Wronskian for a set of two to five functions. The calculator displays the derivative matrix as well as the Wronskian. Links to a derivative calculator and determinant calculator have been provided to assist users in more detailed steps. A related note (link) at the bottom of the page provides users with a brief summary regarding the Wronskian and linear independence of a set of functions.
Potential Effectiveness as a Teaching Tool
Rating:
Strengths:
This calculator could be very useful for students to check their homework solutions or to view step-by-step solutions when they are struggling with some related homework problems. This would be a great resource to share in a Differential Equations course LMS.
Ease of Use for Both Students and Faculty
Rating:
Strengths:
This calculator is easy to use and provides clear solutions. Users can view more details involved in calculating the Wronskian when needed.
Concerns:
This site could be improved by providing a math-type menu for entering the functions. An advertisement appears in between the box where functions that are intended to be entered and the “calculate” button. Depending on the content of this ad, users may be tempted to unwittingly click on the ad by mistake.
