how can i define complex integral in wolfram alpha?
like this?
If you only need to typeset a formula you can do it with the Basic Math Assistant Palette by clicking on the integral box. If you need to calculate a complex integral you can do it with the definition:
c[t_] = Exp[I t];
f[z_] = 1/z;
Integrate[f[c[t]]*c'[t], {t, 0, 2 Pi}]
Thank you
