I'm assuming this is an exhaustive list of indeterminate forms:
$$\infty -\infty, \frac{0}{0}, \frac{\infty}{\infty}, 0 \cdot \infty, 1^\infty, \infty^0, 0^0$$
Are there canonical examples that show why these are considered indeterminate? I presume it means you can have two limits that evaluate to different real numbers and yet if you were to just blindly plug-and-chug directly you could end up with the same indeterminate form?
