# Differential Equations on HP Prime

I have the following differential equation: 3y -5y'=13

Subject to the initial condiction: y(0)=4

In the hp 50g, in RPN Mode, I create a vector with the expressions and the initial condition and invoke the desolve commnad, like this:

[ 3*y(x) - 5*d/dx(y(x))=10   y(0)=4]

y(x)

desolve

That is enough to get the following solution:

13/3 -1/3 e ^ (3/5 x)

The hp prime has a desolve command, but the documentation is so bad and scarse that is is almost impossible to figure out how to solve the problem above, with the initial conditions. I don't even know if it is possible.

Does anyone know how to do it ?

Is there better documentation available?

Thanks

# Re: Differential Equations on HP Prime

Ok.. I figured out how to put the expression and the initial condition in a vector. The rest is basically the same as in the HP50g.  A better user guide is needed URGENT!
