    This video describes Heaviside's methods to quickly decompose a polynomial fraction into its partial fractions. These methods can be used to quickly find the constants in partial fraction decomposition. One method is also called the cover-up method and the other is a comprehensive Heaviside method. We use this method in solving differential equations for example in control system engineering where we need to find the output response of a control system. The classical methods of solving partial fraction problems involve the solution of simultaneous linear equations which is simple but lengthy and user normally do some silly mistakes. These Heaviside methods do not involve linear equations. These methods are very direct methods of finding the constants of partial fraction decomposition. Therefore students of engineering must understand how these methods work and apply these methods when need to find the system output by using the inverse Laplace transform formulas to go from s-domain to time domain. The approach is the use these Heaviside methods to decompose a polynomial fraction into some simpler partial fractions and then take the inverse Laplace transform and get the output of a control system in time domain.
    There are partial fraction formulas used n Heaviside method. One is for constants of non-repeated factors, the second is for the constant of maximum power of repeated factor and the third is to find the constant of other powers of repeated factors. All these three formulas are explained in this video.

    Thanks for sharing! I posted a video on the cover-up method. Hope to get your opinion.
