RE: Solving partial differential equations with the HP Prime and HP 40gs
I am exploring derivatives in the HP Prime.
While this is not solving a pde, I managed to solve a 2nd order ode desolve(4*y''-6*y'+7*y=0) I successfully get G_0*cos(1/4*19^0.5*x) + G_1*sin(1/4*19^0.5*x))*exp(3/4*x) BUT at a later tim I solve the same equation. It now adds the "CAS." before desolve CAS.desolve(4*y''-6*y'+7*y=0) I now get X Error:Syntax Error Why? Thank you Anthony, Sydney |
