2 Differential Equations Apps for iPhone

Plenty of engineers and computer scientists have taken multiple math courses in college. Differential Equations can still prove challenging to students who have had a course or two to prepare for it. These 2 differential equations iPhone apps can help:

XPP: a convenient app for solving various differential equations. XPP will draw nullclines, direction fields, and two- and three-dimensional plots of solutions. You can export data via iTunes.

Slopes: a graphing solution for differential equations. It can dynamically solve systems for up to 6 equations. It comes with 5 activities (Systems, Slopefields, Phase Planes, Waves, and Methods).
