Ordinary Differential Equation - Formula, Definition, Examples
www.cuemath.com › ordinary-differential-equations
The ordinary differential equations would be commonly referred to as only differential equations. The notations used for the derivatives in these ordinary differential equations are dy/dx = y', d 2 y/dx 2 = y'', d 3 y/dx 3 = y''', d n y/dx n = y n. A few examples of ordinary differential equations are as follows. (dy/dx) = sin x (d 2 y/dx 2 ...

Suppose a mass is attached to a spring which exerts an attractive force on the mass proportional to the extension/compression of the spring. For now, we may ignore any other forces (gravity, friction, etc.). We shall write the extension of the spring at a time t as x(t). Now, using Newton's second law we can write (using convenient units):

The order of ordinary differential equations is defined to be the order of the highest derivative that occurs in the equation. The general form of n-th order ODE is given as; F (x, y,y’,….,yn ) = 0. Note that, y’ can be either dy/dx or dy/dt and yn can be either dny/dxn or dny/dtn. An n-th order ordinary differential equations is linear ...
