There is a problem with my grade. My grade for homework 25 got put in twice (once as assignment 25, once as assignment 26). As such, all of my homework grades since then have been shifted by one. Hence, I have a grade for homework 34 despite not having turned it in yet.
This looks like a delta-epsilon proof.
I like the proof "sketch" descriptions. They are very handy.
"Thus we want 3|x 2| < ", or in other words |x 2| < "/3. This tells us what value for delta we should use. "
How does this tell us what value for delta we should use? Upon further reading, I think I might have figured it out. But it'll be good to review. ...Yeah, I figured it out.
This is really cool. I saw a delta-epsilon proof in high school calculus, but I don't think I fully appreciated it at the time.
