Shibberu, Yosi. 2011. MA211 Differential Equations. Class Notes. PowerPoint. 426 slides.

This is a very good set of course slides and the Table of Contents is given here. Since this is a mathematics course taught at an engineering school., Rose-Hulman Institue of Technology, there are many examples from engineering, e.g., circuits and spring mass systems. The material is a mix of exposition (no proofs) of techniques and modeling opportunities with solutions. We give one example here. Example 105 (Minimum Sized Tank) from Slide 255.

“A food processing plant has a problem. Ideally, all the jars of pickled fruit produced by the plant should have the same salt concentration. However, the concentration of the salt solution pumped into jars at 100 gal/hr is observed to vary with time. Assume the salt concentration pumped into the jars is approximated by the function cin(t) = 0.1 sin(t) + 0.2 lbs/gal where t is measured in hours. What should be done to fix this problem?”
