derivative of technology
Let be a function. If, given in the interior of , the limit
exists, then the derivative or differential coefficient of at the point is defined to the value of that limit. As an alternative to (1), the limit
may be used.The value of the derivative at in the interior of is variously denoted
The function is the derivative of the function .
