I need to define two functions for a molecule with speed s.
a)it has a horizontal velocity between s and s b) v , the vertical velocity between +Sqrt[s^2u^2] and Sqrt[s^2u^2] This is what I have done for a)
Thanks a bunch

You mean just
g[s,f[s]] ?

If just insert what you have written I get RandomReal::unifr: "The endpoints specified the uniform distribution range are not real valued I also Tried,
Any ideas?

Definiing two functions (mathematica)
I believe that's because the arguments to RandomReal have to be real. But for example if I entered:
g[2,f[3]] the argument passed to Sqrt results in a complex number. Either need to make sure s^2u^2 is real or either use RandomComplex.
