Collocation method for second order differential equation? - Answers

The collocation method for solving second-order differential equations involves transforming the differential equation into a system of algebraic equations by selecting a set of discrete points (collocation points) within the domain. The solution is approximated using a linear combination of basis functions, typically polynomial, and the coefficients are determined by enforcing the differential equation at the chosen collocation points. This approach allows for greater flexibility in handling complex boundary conditions and non-linear problems. The resulting system is then solved using numerical techniques to obtain an approximate solution to the original differential equation.
