La Hospital's Rule:
L Hospital's Rule is applied only to the two forms .The rule states that if

is of the form then provided later

limit exists. But if still it takes the form then we differentiate numerator

and denominator again.

i.e. and this process continues till we find that

form is removed.

if the function is in form of o/o or infinity /ifinity
then it can be solved using l hspital rule
iit is done by following method
take derivative of num and denominator sperately
(i.e. do not do it as u/v rule but take it differently)
then do it until u get rid of o/o or infinity /infinity form
the answer u will obtain will be the limit if function
