# Math Help - Whats wrong with the integration??

1. ## Whats wrong with the integration??

What wrong with the following 2 integrations:

is z bar.

I looked through it and couldn't find anything. Is there something i am missing?

2. Hello,

If z=a+ib, then $\bar{z}=a-ib$

So when replacing in the second integral, you made a mistake

But the result corresponds to the right thing ? Oo

3. What would be the numerical value of each of the integrals?

Both of these integrals depend on the path you are taking from 0 to 1 + i. For example going from 0 to 1, then from 1 to 1 + i gives (3/2) + (1/2)i. Going along the straight line from 0 to 1 + i gives (1/2)i.
