![]() But there is a method that I find easier. This limit can be solved using L’Hopital’s rule. If you substitute 0, you will find the fraction is the indeterminate form 0/0.

Then subtract the second equation from the first, eliminating the y term. The text translates into the pair of equations: You can skip to the solutions at these times:īelow I’ve summarized the solutions in text. I made a video that explains the problems and their solutions. MindYourDecisions now has over 1,000 free articles with no ads thanks to community support!
