We recall the Legendre transfor-mation connecting the Legendre function L(q, ˙q) with the Hamilton function H(q,p), L q. pq slope: p q −H(p).. where q is the generalized coordi-nated and, ˙q and p respectively the velocity and the momentum, with p = ∂L ∂ ˙q q,
Power Series Solutions to the Legendre Equation
www.iitg.ac.inThe Legendre equation The equation (1 2x )y00 2xy0+ ( + 1)y = 0; (1) where is any real constant, is calledLegendre’s equation. When 2Z+, the equation has polynomial solutions called Legendre polynomials. In fact, these are the same polynomial that encountered earlier in connection with the Gram-Schmidt
Numerical integration: Gaussian quadrature rules
www.dam.brown.eduThe quadrature rules defined above, using the roots of Legendre polynomials as their nodes, are called Gauss–Legendre rules. They have degree of exactness 2n −1 (and order 2n). Gauss–Legendre rules are open rules, and because the nodes are often positioned at irrational points in the interval,
