In this four-lesson series, Professor Burger will look at camouflaged indeterminate forms. Sometimes, we can use mathematical identities or properties to manipulate or re-state an expression such that we can verify that it is an indeterminate form. A limit of a function is called an indeterminate form when it produces a mathematically meaningless expression. Indeterminate forms are also called indeterminant forms.

In these lessons, we'll look at indeterminate products (e.g. 0 times infinity) and indeterminate differences. We'll also use properties of logarithms to restate things like 1^infinity in order to find an indeterminate form that we can the apply L'Hopital's rule to.

Taught by Professor Edward Burger, this series comes from a comprehensive Calculus course. This course and others are available from Thinkwell, Inc. The full course can be found at The full course covers limits, derivatives, implicit differentiation, integration or antidifferentiation, L'Hopital's Rule, functions and their inverses, improper integrals, integral calculus, differential calculus, sequences, series, differential equations, parametric equations, polar coordinates, vector calculus and a variety of other AP Calculus, College Calculus and Calculus II topics.

Thought the video was great

Very helpful for me as I plunge forward in Calc 2. For some reason I was making a minor mistake differentiating the ln(f(x)) portion of this problem. Good to always make sure you are placing items correctly in the numerator or denominator. I was working on a similar problem that was the same except it was 3/x instead of 1/x. Of course the answer is still e! Thanks!
