derivative
derivative Rate of change of the value of a mathematical function with respect to a change in the independent variable. The derivative is an expression of the instantaneous rate of change of the function's value: in general it is itself a function of the variable. An example is obtaining the velocity and acceleration of an object that moves distance x in time t according to the equation x = atn. In such motion, the velocity increases with time. The expression dx/dt, called the first derivative of distance with respect to time, is equal to the velocity of the object; in this example it equals nat(n−1). The result is obtained by differential calculus. In this example, the second derivative, written d2x/dt2, is equal to the acceleration.

derivative
derivative of a formal language. The left-derivative of a language L, with respect to a word w, is {w′ | ww′ ∈ L}
where ww′ is the concatenation of w and w′. Similarly a right-derivative is {w′ | w′w ∈ L} |
