numerical integration - Why Gauss-Legendre Quadrature should keep the number of integral points less than about 50? - Mathematica Stack Exchange
Evaluate the integral of f(x) below between x=0.5 and x=1.5 using Gauss- Legendre formulas for 2, 3, and 4 points. Compare with analytical integration, calculate the % error of the numerical method.
