Hello again,
i'm stuck with the following definitite integral:
As you can see, the function is quadratic in x, but Mathcad Prime isn't able to evaluate the indefinite integral as ist seems. The integration variable should not appear at the right side...
What could be the reason for this behavior?
Many thanks for any Response.
Kind regards, J. Dessecker

Try doing it as follows and then substitute for the constants a, b, c and d in terms of your own parameters (Note that my b is not intended to be the same as yours):
But I don't know why Mathcad objects to your original formulation!
Alan.
If you want to do it all in one go then something like this?
This was done in Prime 2, but I would expect it to work in Prime 3 as well.

Aghhh! You have Prime 3.1, which means I can't open your worksheet, because I only have Prime 3.0 
. If anyone from PTC is reading this, you really need to allow interoperability at least for minor version changes! Not being able to share a worksheet from version 3.0 to version 2.0 is bad, but not being able to share a worksheet from 3.1 to 3.0 is ludicrous!
When I retype your integral it works fine:
Since I can't look at your worksheet the only thing I can say is that Prime sees the x that's the variable of integration as different to the x that's in the kernel. It's not obvious why though. If I change x to y in the kernel I see the same answer you do (except that it has y substituted for x of course).
