Comment	Post #280864	Can you please respond in, by editing, your answer? Comment chains are cumbersome to read. (more)	—	about 3 years ago
Comment	Post #280864	(3) "x has been fixed right at the beginning as an arbitrary positive real number." You spotted my issue! Can you please elaborate? Why can you just assume or deudce that x is fixed? As you wrote, "Stewart expects this to be clear from the phrasing of the exercise itself, and does not begin the solut... (more)	—	about 3 years ago
Comment	Post #280864	Thanks. (1) "I confess I don't see the difference between the two statements." You're correct. There isn't. I edited my post to elaborate. (2) "my variables are " (I think you meant to say "x and m", or "variable is"?) Yes. Thanks. I corrected this. (more)	—	about 3 years ago
Comment	Post #280851	@r~~ Do you mean https://i.imgur.com/i5jxtFW.jpg? "you're using images of text instead of writing your question such that no images are required" Images ARE required. I don't want to mis type the solution manual. I want to show you exactly what it says. (more)	—	about 3 years ago

Comment	Post #280653	@DerekElkins "doesn't simply plotting $x = 1/t$ as a function of $t$ not already make it graphically and intuitively obvious that $t$ approaching $0^\pm$ causes $x$ to approach $\pm\infty$" Perhaps...but how can I visualize this change of variable right in this image, without plotting another graph? ...

Comment	Post #280653	@DerekElkins The first image pictures the LHS, i.e. $\lim\limits_{x \rightarrow \pm \infty} f(x)$. How can I visualize the RHS, or why the LHS = RHS, from this picture alone? (more)	—	about 3 years ago
Comment	Post #280639	Thanks. You're correct that the equality in question isn't in the text. But to clarify, are you implying that I was wrong to equate (32) with (33)? I explained how I did so in the last para. in my question, above the scan. (more)	—	about 3 years ago
