Arc length of parametrically defined curves Ants on a Doughnut. TeX version or Postscript version . If you get the TeX version then you should also get the figures in either Postscript of CorelDraw format. Project contributed by Neal Brand . This project is an introduction to differential geometry.
Students compute lengths of various curves along a torus with the help of a computer.
Project teaches and provides practice in Visualizing in three dimensions Coordinate systems for a surface Parametric curves in three space Use of computers to approximate integrals Arc length of parametrically defined curves Isolating Perry Metric in a Quality Cell. TeX version or Postscript version . Project contributed by Neal Brand . This project is an introduction to the calculus of variation. Students are to investigate the largest area that can be enclosed by a closed curve of fixed length.
