Quadrature, meaning 'finding the [[Area|area]]', also known as [[Quadrature|Numerical Integration]] is the process of finding an [[Integration|Integral]] through [[Approximation]] instead of an analytic solution. Note we typically are referring to [[Signed Area]] in relation to a [[Function]] $f$. $\huge \begin{align} \int_{a}^{b} f(x)\d x \end{align}$ For methods of quadrature, we typically use a 'step size' $h$.
