Asecond order differential equation for the function yt o a differential equation involving the second power of y a differential equation involving the second derivative of y at least two terms involving y o a differential equation involving the square of the first derivative of y

Hi! A second order differential equation for the function y(t) has the next shape:

Where p(t), q(t) and g(t) are functions of t.

Then a second order differential equation for y is a differential equation involving the second derivative of y.

Is useful to remember that the order in a differential equation tells us the number of derivations involved in our function, for example, a "third order differential equation" is that involving the third derivative of y, but usually for orders above of two, are called "higher orders differential equations"
