Derives geometric power series. In a geometric sequence, each term is found by multiplying the previous term by a constant number.
Proof of Isaac Newton generalized binomial theorem. Uses the MacLaurin Series.
Unlike the Taylor series which expresses f(z) as a series of terms with non-negative powers of z, a Laurent series includes terms with negative powers. Therefore, a Laurent series may be used in cases where a Taylor expansion is not possible.

Introduces linear non-homogeneous differential equation with constant coefficients.
