The RLC circuit equation (and pendulum equation) is an ordinary differential equation, or ode, and the diffusion equation is a partial differential equation, or pde. The use of differential equations to understand computer hardware belongs to applied physics or electrical engineering. Learn differential equations applications in terms of solving mathematical problems in Class 11 and 12 and also know its uses in real life with some set of examples. 2.1 Laplace Transform to solve Differential Equation: Ordinary differential equation can be easily solved by the Laplace Transform method without finding the general Learn new and interesting things. Many people make use of linear equations in their daily life, even if they do the calculations in their brain without making a line graph. Growth of microorganisms and Newton’s Law of Cooling are examples of ordinary DEs (ODEs), while conservation of mass and the flow of air over a wing are examples of partial DEs (PDEs). For example, I show how ordinary differential equations arise in classical physics from the fun-damental laws of motion and force. These are second-order differential equations, categorized according to the highest order derivative. Detailed step-by-step analysis is presented to model the engineering problems using differential equa tions from physical principles and to solve the differential equations using the easiest possible method.
