What is the best way to solve a differential equation?
Problem-Solving Strategy: Separation of Variables
Rewrite the differential equation in the form dyg(y)=f(x)dx. Integrate both sides of the equation. Solve the resulting equation for y if possible. If an initial condition exists, substitute the appropriate values for x and y into the equation and solve for the constant.How to solve differential equation by separation of variables?
As we can see from the above table, the method used for solving an ordinary differential equation is the Runge Kutta method, and the above-given equation, i.e, d y d x = f ( x , y ) for gradually varied flow profile is an ordinary differential equation.
