    Question on L'H˘pital's Rule.

    Can someone explain how to tell the form?
    Whether it is...

    \frac{\infty}{\infty}

    \frac{0}{0}

    And later there are indeterminate forms.

    1^{\infty} or        0^0 or        \infty^0

    How do you tell what form it is in?

    Re: Question on L'H˘pital's Rule.

    If I understand your question correctly ... simply plug the value for the limit into the numerator and denominator and see what they become. For example given

     \lim _{x \to 0} \frac {\sin x}{x} if you substitute 0 for x you get  \frac {\sin 0}{0} = \frac 0 0
