parameterization of circular arcs
Im trying to evaluate a complex integral whose image is the circular arc in an anticlockwise direction
for arcs considered in a clockwise direction we have
does anyone know how i could solve an integral in the anticlockwise direction
many thanks

Re: parameterization of circular arcs
Make t negative. You may have to re-parametrize t if your arc is not a full circle.
