Computed Tomography in Multivariable Calculus (UMAP)
Yves Nievergelt
|
Mathematics Topic:
Calculus 3 |
Application Areas:
Medicine, imaging |
Prerequisites:
In general: the ability to ponder a problem that does not come with a canned recipe for its solution. In particular, from multivariable calculus: limits and partial derivatives of elementary (rational, trigonometric, or exponential) functions, integrals along lines in the plane and along lines or planes in space, changes and permutations of variables in multivariable integrals, dot products, and small linear systems. |

This module seeks to: 1) strengthen students' intuition in multidimensional geometry; 2) consolidate students' command of multivariable integrals; 3) provide exercises at a level between mechanical and theoretical; and 4) show applications of calculus that are important but rarely appear in calculus texts. This module provides exercises with line integrals and multivariable integrals for use in multivariable calculus courses, at a level intermediate between mechanical problems and abstract proofs. The exercises do not require any background on any applications.
