## anonymous 5 years ago I have another complex analysis question for this week....can anyone help??

1. anonymous

$\int\limits_{?}^{?}1/z^3 dz$

lokisan helped me last week :-)

to be sure I am seeing it right; that is the integral of 1/(z cubed) with respect to z right?

4. amistre64

if we change the expression so that it is just a variable and an exponent, itll be easier

5. amistre64

$1/z^{3} = z^{-3}$

6. amistre64

$\int\limits_{} z^{-3} dx \rightarrow (z^{-3+1})/(-3+1)$

7. amistre64

or simply:$[1/(2z^{2})] + C$

8. amistre64

make that negative :) i lost the negative somewhere :)
