Exploring Multivariable Calculus!
Welcome to Exploring Multivariable Calculus! This website is dedicated to helping you explore multivariable calculus, differential equations, and some three-dimensional topics within linear algebra and single variable calculus.
Watch a 3-minute video about this project on the 2020 STEM for all Video Showcase.
As you explore the visualization tools found on this site, I think you will enrich your understanding of the geometric aspects of the concepts of multivariable calculus, differential equations, and single-variable calculus. My goal is to enhance the geometric intuition of calculus students so that they are able to visualize the concepts and actually “see” the rich visual relationships and interactions described by the calculus concepts.
As an instructor, I often found it difficult to draw the three-dimensional concepts clearly on the chalkboard and found myself waving my hands to try to get students to see what I was seeing. Using these visualization tools, I can show students a much clearer picture of what I have been describing verbally.
There are even some new features introduced in the new app, including:
- The user can create 3D regions with top and bottom surfaces as well as being restricted to a 2D domain in the xy-plane specified by two functions of x or of y.
- The user can vary the rectangular uv-domain of a parametric surface in the 2D trace plane.
This web project is being developed with support from the National Science Foundation under the grants, NSF-IUSE 2121152 (2021-Present), DUE-IUSE 1524968 (2015-2019) and DUE-CCLI 0736968 (2008-2012). Some support was also received from two Xerox STEM grants.
