Quadrature (mathematics) - Wikipedia
In mathematics, quadrature is a historic term for the computation of areas and is thus used for computation of integrals. The word is derived from the Latin quadratus meaning "square". The reason is that, for Ancient Greek mathematicians, the computation of an area consisted of constructing a square of the same area. en.wikipedia.org

Numerical integration/Quadrature I want to find constants a, b, c and d that will produce a quadrature formula: $$\int_{-1}^{1} af(-1) + bf(1) +cf'(-1)+df'(1)$$ that has degree of precision 3. I'm not sure how to g...
**Hint** : It is solvable by setting up a system of four equations in four unknowns. We are given: $$\int_{-1}^{1} af(-1) + bf(1) +cf'(-1)+df'(1)$$ I will do the first and you can do the rest: $$f(x) = x^0 = 1 \implies \displaystyle \int_{-1}^1 ~ 1~ dx = 2 = a(1) + b(1) + c(0) + d(0) $$ Now repeat t...
