The subject calculus is one of the branches of Mathematics and was found by Newton and Leibniz. This is primarily concerned with two basic operations called differentiation and integration. In this section ; we shall briefly formalize the idea of differentiation in terms of the notion of the limit of a function.
Derivative:
A function f(x) is said to be derivable if:
exists.
We write read it as differential coefficient of f(x) with respect to x.
A function f(x) is said to be right hand Read more [...]
