WebJul 9, 2024 · Thus, the general solution is y(x) = c1cos(√λ + 2ln x ) + c2sin(√λ + 2ln x ). Next we apply the boundary conditions. y′(1) = 0 forces c2 = 0. This leaves y(x) = c1cos(√λ + 2lnx). The second condition, y′(2) = 0, yields sin(√λ + 2ln2) = 0. This will give nontrivial solutions when √λ + 2ln2 = nπ, n = 0, 1, 2, 3….

WebOct 25, 2024 · The book presents in comprehensive detail numerical solutions to boundary value problems of a number of non-linear differential equations. Replacing derivatives by finite difference approximations in these differential equations leads to a system of non-linear algebraic equations which we have solved using Newton’s iterative method.
