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]
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?
Please, don't reference the user guide. I already verified it.

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!
