## Lecture 11: 2nd order ODE with constant coeffcients non-standard method of solution

4.1 ( 11 )

###### Lecture Details

Free ebook httptinyurl.comEngMathYTI present a direct and non-standard method of solution to the 2nd order homogeneous ODE with constant coefficients, namelyy - 4y + 4y = 0.I do not explicitly use the characteristic equation, rather I reduce the problem to the analysis of a first order ODE. Such a method shows exactly why the solution features exponential functions and illustrates where they come from,
