Question: Solving ODEs with parametric ICs

Hi !

I wish to solve a differential equation with an initial condition of the type D(f)(a)=b, where 'a' and 'b' are arbitrary real constants and are entered this way symbolically. Maple interprets D(f)(a) as a function which depends on a new variable 'a' and gives the error:


Error, (in dsolve) found differentiated functions with same name but depending on different arguments in the given DE system: {f(a), f(psi)}

(the differential equation is for a function f(psi) which was defined previously)


How can I pass this initial condition f'(a)=b (a,b being constants, but arbitrary) to the Maple dsolve command?

I have been browsing the web and looking at manuals, but always find D(f)(0)=3 or any other combination with numbers only.

Thank you in advance.
