Thread: Indeterminate Form Discussion - 1^(inf)

In my AP Calculus class, we had a lengthy discussion regarding the indeterminate form . Other bases to infinity either turn out to be infinity itself or 0, depending on the base. To me, that doesn't make sense. Why are quantities, such as , are determinate, but is not? Just want to hear some opinions.

Dr. Math discusses why ...
