greens fnc problem
solve the given boundary value problem by determining the appropriate greens function i) as eigenfunction expansion ii)in closed form and express the solution as a definite integral
y'' + y = - f(x) y'(0) = 0, y(1)= 0
i want to learn how to solve this question to progress in this field.
Then take a course and/or get a good text! You certainly aren't going to learn by asking others to solve the problem for you.
