Left Hand Limit: Let f (x) tends to a limit l1 as x tends to through values less than 'a', then l1 is known as left hand limit.
Right Hand Limit: Let f (x) tends to a limit l2 as x tends to 'a' through values greater than 'a', then l2 is known as right hand limit.
Limit of f (x) subsist at x = a, if l1 & l2 are both equal & finite.
The concept of limits leads to describe & define continuity & derivative of the function. The continuity of a function has theoretical importance as well as practical importance. Plot graphs by taking the values produced in the laboratory or collected in the field & connect the plotted points with a smooth and unbroken curve.
In our next blog we shall learn about theory of relativity for dummies I hope the above explanation was useful.Keep reading and leave your comments.
