I use Maple 9 for some weeks and it helps me a lot. In the last days I have 2 problems that I could not implement in Maple. I spent many hours reading manuals, tips etc. without finding an idea, so I decided to post here my questions:
I use dsolve (numeric) to solve a system of ODEs. I receive the solution "p" wich I can plot whithout problems.
After this, I define a new function "S" as:
S := t -> p(t) + p(t) + p(t) + p(t);
I tried to plot it with
but I receive the message
Warning, unable to evaluate the function to numeric values in the region; see the plotting
command's help page to ensure the calling sequence is correct
Error, empty plot
The function "S" is defined in that region, and I can read some values, when I give e.g.:
How could I plot this function?
I define a function and an equation as:
PH := t -> p(t) + 2*p(t);
But this gives me the message:
Error, (in fsolve/Iterators) not implemented yet 4
Is there a solution to this?
I would be grateful for any help.
