I’m looking for ways that I might be able to check student answers that involve multiple variables and items like “dy/dx” or “dr/dt”, etc.
I usually use simpleFunction to check answers but that doesn’t work with variables like “dy/dx”.
Currently, the only way I can think of is to check their raw latex. That’s generally messy as there are too many possibilities for an answer.
For example, I want a student to find the derivative V=pir^3 or V=\frac{4}{3}\pi r^{3} with respect to t, so the student input to check would be dV/dt=4pir^2 *dr/dt or \frac{dV}{dt}=4\pi r^{2}\cdot\frac{dr}{dt}.
Any other ideas besides checking raw latex of the input?
Parse equation?
Graphs?
Thanks!
