WebNov 8, 2024 · Wave Functions. We will discuss a clever way of deriving the stationary-state wave functions below, but we will start here by simply stating the ground state wave function in position space. The functional form is that of a gaussian ( f ( x) = e − α x 2), which when normalized looks like: (3.3.3) ψ o ( x) = ( β π) 1 2 e − ( β x) 2 2 ... WebGaussian quadrature is an amazing technique for numerical inte-gration. Generally when interpolating polynomials one needs n+1 points to interpolate an nth degree polynomial. The same could be expected for numerical integration. However Gaussian quadrature integrates polynomials of degree 2n + 1 exactly with n + 1 points. This is a very ...

WebIn numerical analysis, Gauss–Legendre quadrature is a form of Gaussian quadrature for approximating the definite integral of a function. For integrating over the interval [−1, 1], the rule takes the form: where n is the number of sample points used, wi are quadrature weights, and xi are the roots of the n th Legendre polynomial.
