ABSTRACT
Differentiation is a process in calculus used to express the rate of change of a given function with respect to location or time. If there is a function f(x) that is analytic in the given range of the independent variable x, the first derivative of the function, denoted by f’(x) is defined by f ′ ( x ) = Lt h → 0 f ( x + h ) − f ( x ) h https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315137650/8059e074-83e2-41cd-9e27-071a29016669/content/eq106.tif"/>
