State and prove Cauchys integral theorem?

Cauchy's Integral Theorem states that if ( f ) is a holomorphic function on a simply connected domain ( D ), then for any closed curve ( C ) within ( D ), the integral of ( f ) over ( C ) is zero:

[ \oint_C f(z) , dz = 0. ]

Proof Outline: Let ( f ) be holomorphic in ( D ) and ( C ) a closed curve in ( D ). Since ( f ) is holomorphic, it is differentiable everywhere in ( D ), and we can apply Green's Theorem in the plane, which relates the line integral around a closed curve to a double integral over the region ( R ) enclosed by ( C ). Since the partial derivatives of ( f ) are continuous, the integral of the derivatives over ( R ) is zero, thus confirming the result ( \oint_C f(z) , dz = 0 ).

Who was the German astronomer and mathematician developed 3 laws?

How do you derive poisson's equation from laplace equation?

Poisson's equation is a generalization of Laplace's equation. While Laplace's equation states that the Laplacian of a scalar potential ( \phi ) is zero ((\nabla^2 \phi = 0)), Poisson's equation includes a source term, expressed as (\nabla^2 \phi = -\rho/\epsilon), where (\rho) represents the source density and (\epsilon) is a constant related to the medium. To derive Poisson's equation from Laplace's equation, one can consider a situation where there are charges or mass densities present, leading to a non-zero right-hand side in the equation. Thus, Poisson's equation describes the potential field generated by such sources, while Laplace's equation applies in regions devoid of sources.

What is the ancient Greek mathematician estimated the most accurate calculations of pi of his times?
