### Introduction

The derivative,
$\frac{dy}{dx}$
, is more expressly called the
**
first derivative
**
of
$y$
. By differentiating the first derivative, we obtain the
**
second derivative
**
; by differentiating the second derivative we obtain the
**
third derivative
**
and so on. These second and subsequent derivatives are known as
**
higher derivatives
**
. Second derivatives in particular occur frequently in engineering contexts.
