Hi,
I’m trying a simple derivation with mathcad 15. At least I thought it was easy.
The function is
I want Mathcad to calculate
But the outcome is obviously missing a term…
Check the attachment for the corresponding xmcd or png.
Can somebody tell me what’s wrong?

Solved! Go to Solution.

Yes, Mathcad is often very (too) tolerant in this respect, but its wrong from a mathematical point of view to use the same variable for limit AND integration variable as you had done. Use different variables and all works OK.
Mathcads behavior nevertheless is wrong - it should throw an error message instead of yielding a wrong result.
