# Indeterminate form

An indeterminate form is an expression in calculus obtained from calculating the limit of a function, and whose numerical value is not able to be determined. However, the limit of such a function can often be determined using a technique such as L'Hôpital's Rule.

Basic indeterminate forms for limits:

${0\over 0}\qquad {\infty\over\infty}$

Other indeterminate forms for limits, that can usually be simplified into the basic forms when the original problem is manipulated:

${\infty^0\qquad 1^\infty\qquad 0\cdot\infty\qquad 0^0\qquad\infty - \infty\qquad}$
