Differential Equations
The HP 48 can find a solution, to a differential equation
expressed as y'(i) = where the initial value of the solution is
given as y{to) = yo.
Solving Differential Equations
The differential equation solver is part of the SOLVE application.
To use the SOLVE differential equation solwer:
