Numerical integration/gauss-legendre quadrature you are encouraged to solve this task according to the task description, using any language you may know. Numerical integration is the term used for a number of methods to find an approximation for an integral numerical integration has also been called quadrature. The fundamental theorem of calculus gives us an exact formula for computing $\int_{a}^{b}\ f(x)\ dx,$ provided we can find an antiderivative for $f$ this method of evaluating definite. Numerical methods often, we need to find the integral of a function that may be difficult to integrate analytically (ie, as a definite integral) or impossible (the function only existing.
