Hey,
I'd like to simplify a following type of sum:
In[62]:= Sum[a[k]*I + b[k], {k, 1, n}] - I*Sum[a[k], {k, 1, n}] -
Sum[b[k], {k, 1, n}]
In[63]:= FullSimplify[%]
The result should obviously be zero; however, Mathematica returns the same expression. If I put n an integer value it knows how to simplify. How do I make it understand that also with a symbolic upper limit?
Hope someone can help!
Thanks,
Lari
