I have a question about numerical integration in Maple. I have an equation (a PDF) which I need a numerical answer from as Maple can't find a closed form solution (which isn't too surprising given the equation in question). Anyway, the equation has several parameters which are varied and the equation looped over. That's no problem, and generally Maple will find a numerical solution to the problem. However, towards the extreme value case I get error messages basically saying Maple hasn't found a numerical result.
The equation giving the error is:
-20.01782577 I exp(-490.0000000 - 50. x) (-0.1625801243 10^212 I + erf(0.2258769757 I (9801. + 980. x)^1/2 - 0.2258769757 I)) dx
integrated over x from 0 to 30. Maple just churns a lot and then prints my equation back out.
Does this mean I've hit some kind of limit with Maples numerical computations? I realised that -0.16... 10^212 is a phenomenally large negative number. Can anyone suggest a way of over coming this, or can it just not be done?
Thanks for you help,
