This is a question from a beginner:
ff[z_] = 1/z + z^3
Integrate[ff[z], {z, y, y0}]
intff[z_] = Integrate[ff[z], z]
intff[y] - intff[y0]
I expected to get same results from line 2 and line 4. However, the output
from line 2 is very complicated, with an If which has Im(y) and Im(y0)
involved. The result I want is that from line 4. How can I modify line 2
so that it produces the same output as from line 4?
Thanks.
