Cauchy formula

Holomorphic-function value at origin {Cauchy formula} is (1 / (2 * pi * i)) * contour integral (f(z)/z) * dz. Holomorphic-function value at point p is (1 / (2 * pi * i)) * contour integral (f(z)/(z - p)) * dz. Holomorphic-function nth-derivative value at origin is (n! / (2 * pi * i)) * contour integral (f(z)/z^(n + 1)) * dz.
