Hi, I have a question regarding usage of solution given by NDSolve function Suppose We have solved one ODE with NDSolve, it will give the solution as interpolating function. Suppose I am solving a ODE for solution of y as a function of x, I will get solution like {y -> InterpolatingFunction[{{0., 1.}}, <>]}. Now I can get the values of y at any x using y[x]/.sol/.x->0.5 But Suppose I want to evaluate the y' [x](Derivative of y) how can we get it that from the solution of NDSolve Thank you
