The general method for solving a differential equation depends on the type of equation. There are several different techniques used to solve different types of differential equations, including separation of variables, integrating factors, exact equations, and many more.

Here is an example of solving a first-order ordinary differential equation using the separation of variables method:

Separate the variables: Write the differential equation in the form dy/dx = f(x)g(y), where f(x) is a function of x only and g(y) is a function of y only.

Integrate both sides: Integrate both sides with respect to x and y separately to obtain âˆ«1/g(y) dy = âˆ«f(x) dx.

Solve for y: Evaluate the integral on the left-hand side to obtain y as a function of some constant of integration C.

Substitute the constant: Use any initial conditions to solve for the constant C.

Here is an example of a differential equation and how to solve it using the above method:

dy/dx = x/y

Separate the variables: y dy = x dx.

Integrate both sides: âˆ«y dy = âˆ«x dx, giving (1/2)y^2 = (1/2)x^2 + C.

Solve for y: Solve for y to obtain y = Â±sqrt(x^2 + C).

Substitute the constant: If y(0) = 1, then C = 1, and the solution is y = Â±sqrt(x^2 + 1).

Note that the Â± sign is included because there are two solutions to the differential equation, depending on the initial condition.
