  2. 1-015-Text-S-DimensionlessVariables

    25 Aug 2018 | | Contributor(s):: Kurt Bryan

    This material introduces the idea of ``rescaling'' for ordinary differential equations (ODE's) by the introduction of dimensionless variables. In practice this is an extremely common and useful prelude to the analysis and solution of ODE's, and yet is not often taught in an...

  3. 1-071-S-NewtonWatsonTimeOfDeath

    28 Aug 2017 | | Contributor(s):: Brian Winkel

    Sherlock Holmes determines the time of death for a body found on a street in London and we need to reproduce his astute analysis.

  4. 2011-Leinbach, Carl - Beyond Newton's law of cooling – estimation of time since death

    02 Mar 2017 | | Contributor(s):: Brian Winkel

    Leinbach, Carl. 2011. Beyond Newton’s law of cooling – estimation of time since death. International Journal of Mathematical Education in Science and Technology. 42(6): 765-774.Article Abstract: The estimate of the time since death and, thus, the time of death is strictly that, an...

  7. 1994-Gruszka, T. - A Balloon Experiment in the Classroom

    20 Jun 2015 | | Contributor(s):: T. Gruszka

    Gruszka, T. 1994. A Balloon Experiment in the Classroom. The College Mathematics Journal. 25(5): 442-444.See https://www.tandfonline.com/doi/abs/10.1080/07468342.1994.11973649 .We quote from the article,“The following experiment involves a balloon, a stopwatch, and a...

  8. 7-005-S-Text-LaplaceTransformOverview

    06 Jun 2015 | | Contributor(s):: Brian Winkel

    The Laplace Transform is a mathematical construct that has proven very useful in both solving and understanding differential equations. We introduce it and show its power here. This is done in a Mathematica notebook with pdf provided. 

  9. 1-013-S-Sleuthing

    03 Jun 2015 | | Contributor(s):: Brian Winkel

    We present several situations in which differential equation models serve to aid in sleuthing and general investigations. One involves initial speed given information about constant deceleration and distance to stop in traffic incident; one involves modeling a steel ball launched vertically and...

  10. 1-045-S-TimeOfDeath

    02 Jun 2015 | | Contributor(s):: Brian Winkel

    Students are asked to determine the time of death given both environmental temperature situations and two observations of body temperature under several different circumstances.
