In this video, we will start with Second and Higher-order ordinary differential equations. We will see the concept of higher-order linear differential equations followed by Initial value problem then Basis and General solution. This is the first part, in which I will talk about higher-order ODE with examples and superposition or linearity principle along with some counterexamples. This is given in the 2nd and 3rd Chapter of Erwin Kreyszig but I will be taking them simultaneously for better understanding. I will also give a flavor of linear algebra to make it a little interesting! ===================================== Link to part II of this lecture: https://www.youtube.com/watch?v=M7eNGMD-YEc
