To evaluate `lim_(xtoa)[f(x)]`, we must analyse the `f(x)` in right hand neighbourhood as well as in left hand neighbourhood of `x=a`. E.g. In case of continuous function, we may come across followign cases.


`If `f(a) is an integer, the limit will exist in Case III and Case IV but not in Case I and Case II.`lim_(xto1)["cosec"(pix)/2]^(-1//(1-x))` is equal to (where [.] denotes the greatest integer function).

To evaluate lim_(xtoa)[f(x)] , we must analyse the f(x) in right hand neighbourhood as well as in left hand neighbourhood of x=a . E.g. In case of continuous function, we may come across followign cases. If f(a) is an integer, the limit will exist in Case III and Case IV but not in Case I and Case II. If f(a) is not an integer, the limit exists in all the cases. ltbgt If f'(1)=-3 and lim_(xto1)[f(x)-1/2] does not exist, (where [.] denotes the greatest integer function), then
