ABSTRACT
This chapter discusses the functional notation of an equation with an example. Infinity is not a number in the sense that it can be multiplied or divided. Rather it stands for the statement that a number is extremely large. The chapter explains the concept of limits by using an equation. The mathematical process of finding an expression for the gradient of a curve at any point is called differentiation. The chapter illustrates differentiation of an equation having two constants. It discusses the differentiation of polynomials, differentiation of a function of a function, differentiation of the product of two functions, differentiation of a quotient of two functions, differentiation of an implicit function, and differentiation of the inverse trigonometric functions.
