Higher Derivatives
Suppose that there is the differentiable function y=f(x), i.e., there is the derivative y¢=f¢(x), which is denoted by f1(x). Definition. The derivative of the derivative of function is called the second derivative; the derivative of the second derivative of function is called the derivative of the third order respectively and is denoted by
.......
etc. Notations:
are read, for example, the third derivative – d three y with respect to the third power of dx.
