A really cool discussion of indeterminate forms

I was working on a difficult limits problem from Reddit (r/Calculus) over coffee this morning, and a Google search led me to this discussion. I wanted to shout this out!

For Calculus students, this topic can be very tricky. What I liked about this discussion was not only how they enumerated the “standard” indeterminate forms, but how they also discussed problem solving approaches to dealing with each one, mostly around transforming from one type to another, especially in terms of setting up limit problems for L’Hôpital’s Rule or for a really cool algebra trick. Check it out!

Happy 2022 to all of my readers!
