when the limit is of the form 0/0 or then find the derivative of the func till the above two forms get eliminated.

 rate if helpful

It is applicable only for     which either 0/0 form or infinity/infinity form.

If the given limit is either of the above mentioned forms, differentiate f(x) and g(x) separately

i.e  lim x-->a  f ' (x)/g ' (x)

Even after differentiation if it is of the same form then do repeated differentiation

i.e f " (x)/g " (x) 

example:

lim x--> 0  x/x
