A function may approach two different limits. One where the variable approaches its limit through values larger than the limit and the other where the variable approaches its limit through values smaller than the limit. In such a case, the limit is not defined but the right and left-hand limits exist. When the limx→af(x)=A+limx→af(x)=A+ given the values of f… Continue reading Limits and Functions

Here are some properties of the limits of the function: If limits limx→alimx→a f(x) and limx→alimx→a g(x) exists, and n is an integer, then, Law of Addition: limx→a[f(x)+g(x)]=limx→af(x)+limx→ag(x)limx→a[f(x)+g(x)]=limx→af(x)+limx→ag(x) Law of Subtraction: limx→a[f(x)−g(x)]=limx→af(x)−limx→ag(x)limx→a[f(x)−g(x)]=limx→af(x)−limx→ag(x) Law of Multiplication: limx→a[f(x)⋅g(x)]=limx→af(x)⋅limx→ag(x)limx→a[f(x)⋅g(x)]=limx→af(x)⋅limx→ag(x) Law of Division: limx→a[f(x)g(x)]=limx→af(x)limx→ag(x), where limx→ag(x)≠0limx→a[f(x)g(x)]=limx→af(x)limx→ag(x), where limx→ag(x)≠0 Law of Power: limx→ac=c

Limits in maths are unique real numbers. Let us consider a real-valued function “f” and the real number “c”, the limit is normally defined as limx→cf(x)=Llimx→cf(x)=L. It is read as “the limit of f of x, as x approaches c equals L”. The “lim” shows the limit, and fact that function f(x) approaches the limit L as x… Continue reading What Are Limits?
