limit is a number that a certain function(lets say of x) approaches as x aprroaches some value
this value of limit is defined only when the approach of x from a value slightly lesser than the given value and slightly greater than the given value gives the same result in both cases
i.e
if x approaches say 0 then approach of x from values slightly less than 0 and slightly more than 0 will lead to the function value approaching the same number
when this is not true limit will not exist
