if in limits both the numerator and denominator are turning out to be zero i.e. 0/0 form then the numerator and denominator are differentiated individually and the limit is found.

if this to is of 0/0 form the process must be continued till the 0/0 form is not obtained.

please note that infinity/infinity must be converted to 0/0.

example:

limit (sin(x)-x)/sin(x)
x->0

=

limit (cos(x)-1)/cos(x) = 0
x->0

mate,
       u're probabely gonna get it in any good books.
its like in a limit in the form a/b where a n b are te func of x it the limit is in the 0 by 0 form i.e by puttin the limiting value in the numerator n the denominater we get 0/0 form the limit is solved by deriving the numerator n denominater  separately .then if its still in the 0/0 form just continue doin it untill the ans is got . but ber sure to check whether the limit atll exists or not at the given limiting value before proceedin to do the limit in the 1st place
