- A differential equation involving derivatives of the dependent variable with respect to only one independent variable is called an ordinary differential equation.
- A differential equation involving derivatives of the dependent variable with respect to more than one independent v
- Some differential equations can be solved by the method of separation of variables.
- (dy/dx) = f(x, y) is a first order and first degree differential equation. If f(x, y) can be written as h(x).g(y), where h(x) is a function of x and g(y) is a function of y, then we can separate
• In order to understand homogeneous differential equations, it is important to understand homogeneous function. A function f(x, y) is called a homogeneous function of degree n, if a function f can be expressed as follows:
