Binomial Expansion
(1 + x)^n = 1 + n*x + n(n-1)*x^2/2! + n(n-1)(n-2)*x^3/3! + ..... + n(n-1)(n-2)..(n-k+1)*x^k/k! + ...
Taylor Series
f(x + h) = f(x) + h*f'(x) + h^2*f''(x)/2! + ... + h^k*f^k(x)/k!...
Exponential Series
e^x = 1 + x + x^2/2! + x^3/3! + ... + x^k/k! + ...
Logarithmic Series
Log(1 + x) = x - x^2/2 + x^3/3 - x^4/4 + ... +
(-1)^k+1*x^k/k + ........
