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. lim_(xto0)[(1-e^(x)).(sinx)/(|x|)] (where [.] denotes the greatest integer function) equals
