Electrical engineering is an engineering discipline concerned with the study, design, and application of equipment, devices, and systems which use electricity, electronics, and electromagnetism.

Equation 3 is a second-order linear differential equation and its auxiliary equation is. The roots are We need to discuss three cases. CASE I (overdamping) In this case and are distinct real roots and Since , , and are all positive, we have , so the roots and given by Equations 4 must both be negative. This shows that as . Typical graphs of

08.07.2017 · Ordinary Differential Equations come up whenever you have an exact relationship between variables and their rates. Therefore you can happen them in geometry, economic sciences, technology, ecology, mechanics, phys- iology, and many other topics. For case, they describe geodesics in geometry, and viing species in ecology. ITS Application:

Application 1 : Exponential Growth - Population. Let P (t) be a quantity that increases with time t and the rate of increase is proportional to the same quantity P as follows. d P / d t = k P. where d p / d t is the first derivative of P, k > 0 and t is the time. The solution to the above first order differential equation is given by.

A differential equation (DE) is an equation in which an unknown function y(t) appears together with some of its derivatives. In general, a DE can be written as.
