can data builder do dflux / dt ?

i am trying to design an activities something like modelling for learners to key in data function
slope = dflux / dt

and compare with emf graph

to conclude - slope =  emf

thus  - dflux / dt =  emf

in principle, it should be do-able because in tracker it also has derivatives of sx sy in the form of vx and vy.

any tips?
