[Maths Class Notes] on How to Solve Linear Differential Equation? Pdf for Exam

Linear differentiation equation is a form of the equation that is linear and polynomial. It is a part of the new derivatives and functions of an equation of a structure. A linear equation usually consists of derivatives of multiple variables. When a result and variable is partial, then it is also stated as a linear partial differential equation.

In an equation when its new function and the derivative is not in the linear form, it is then considered to be a nonlinear differential equation. It is used to find a solution for multiple chaoses.

In an equation where x dy / dx + Y = 0, it involves variables and a derivative which is dependent on y variable linked to independent variable x. This form of an equation is called a differential equation. Usually, an equation with a result of dependent variable connected to independent variables is known as a differential equation. It involves dependent variable derivatives concerning a single independent variable, also known as an ordinary differential equation.

Apart from these, students get to learn about the first-order nonlinear differential equation and first-order linear differential equation. Here the variables like P and Q works as an independent variable or remain constant.

The equation dy/dx + Py = Q can be a form of differential equation in a first-order linear differential. Here P and Q can be either function of y, which is an independent variable or constants only. A student has to derive the standard form or a depiction of this solution.

How to Solve First Order Nonlinear Differential Equation

A first-order differential equation is considered to be separable if it can be written in the form ϕ(y)dy = ψ(x)dx. This suggests the official process of anti differentiating ϕ(y) and ψ(x) concerning y and x. Moreover, results to arrive at an implicit general solution is equated as Z ϕ(y)dy = Z ψ(x)dx + C. It is important to note that here R ϕ(y)dy and R ψ(x)dx stand for definite antiderivatives of ϕ(y) and ψ(x).

The nonlinear differential equations definition can be understood from this explanation. In a nonlinear system of equations cannot be written or solved as a linear combination of new function or variable. A system can be termed as nonlinear despite a linear function shows in an equation. In other words, a differential equation can be linear when its the unknown function and derivatives are linear in terms. This will be same even if the other variables in terms of nonlinear appears.

Apart from the nonlinear differential equation, students need to practice equation based on linear equations. They should follow quality test papers and exercise materials, offering multiple questions on how to solve a nonlinear differential equation.
