How do we/ can we find the solution of a differential eq d^3y/dx^3 + d^2y/dx^2 - dy/dx =0?
A differential equation is a mathematical equation that relates one or more functions and their derivatives. It describes how a quantity changes over time or in relation to other variables.
The purpose of solving a differential equation is to find the function(s) that satisfy the equation and represent the behavior of a system. This allows us to make predictions and understand the underlying principles governing the system.
The most common methods for solving differential equations are separation of variables, substitution, integration, and using special functions such as Laplace transforms or power series.
To verify the solution of a differential equation, you can substitute the proposed solution into the original equation and see if it satisfies the equation. Another method is to plot the solution and see if it matches the expected behavior of the system.
Differential equations are used in many fields of science, including physics, chemistry, biology, engineering, and economics. They are used to model and understand complex systems, such as the motion of objects, population growth, chemical reactions, and electrical circuits.
