« In general the limit of φ(x)/ψ(x) when 1=x = a in case the limits of both the functions exist is equal to the limit of the numerator divided by the denominator. But what happens when both limits are zero? The division (0/0) then becomes meaningless. A case like this is known as an indeterminate form. Other such forms are ∞/∞ 0 × ∞, ∞ − ∞, 00, 1∞ and ∞0. »
