This chapter discusses the second-order differential operators. The chapter proves a general existence and uniqueness theorem for solutions of a second-order linear differential equation. The equations are considered relative to a closed, finite interval [,] and are of the form. One may require ...

We can solve a second order differential equation of the type: d2ydx2 + P(x)dydx + Q(x)y = f(x) where P(x), Q(x) and f(x) are functions of x, by using: Undetermined Coefficients which only works when f(x) is a polynomial, exponential, sine, cosine or a linear combination...
叔的饼上回烤了一半,今天接着烤。今天解决的是:second order differential equations,二阶微分方程。这回就难一些了。为毛呢?这还用叔说么,你烤两层的饼,肯定要比烤一层的饼费一番功夫了!这还用叔说,真是的,没吃过饼,还没看过...
