Limit of a function at a point may or may not exist. If limit of a function is not exist then may be + or - . If limit of a sequence does not exist then it is called as a divergent sequence. It may be divergent to + or divergent to - .Limits at Infinity has two possibilities one is positive side and other is negative side. For some sequences there may not exist finite or infinite limit values.
Infinite Limits are the limits for which limit value does not exist. When we are finding limit for the division of two functions if it does not exist then we can use L-Hospital rule to find out the limit value. L-Hospital rule states that, if we are getting
form when we are finding limit for division of two functions then first differentiate numerator and denominator and then apply limit.
