L'Hôpital's rule can be used on other kinds of limits if they can be manipulated so as to require the evaluation of a 0/0 or ∞/∞ limit e g , find lim x→∞ ( 1 + a

Using the definition of the limit, limx→a f(x), we can derive many general laws of limits, that help us to calculate limx→0+ 0 = 0 and limx→0− (1 x − 1 x )

The limits are defined as the value that the function approaches as it goes to an x value Using this definition it is possible to find the value of the limits
