Anyone with knowledge on the HP 49G

[Belegost]

I just got myself one, and the user manual is a bit sparse on how to use the commands. I'd really like to know what commands are used to solve (symbolically) differential equations, I can find the base function for it, but I can't figure out the syntax to tell the calculator which variable is independent. This is he first time I've used an HP caclulator (I've always used TI in the past.) so any help would be appreciated.
