Thanks for the posting and reply, Curious3141. Originally, when I first read the document, I thought it said, "e^2pi," which would be 535.4916555. But it doesn't say that. It says "e^ipi." I had never seen or heard of this term before. Obviously this makes the answer to the term and ultimately...

No problem, Chris. Here is one more for each PFer that views this thread. It is by Harvey Mudd College in California http://www.math.hmc.edu/calculus/tutorials/ It has an Algebra review but mostly focuses on Pre-Calculus to Differentials. Either way, it is a great source for working ahead or...

Thanks for the reply and information, micromass. I do appreciate it.

Thanks for your posting, Fredrik.

Just out of curiosity, what level algebra is this symbolism used for? This is the first time I've seen it. I am familiar with max and min, just not in this notation. Thanks.

First and foremost, thank you so much for the responses my friends. I do appreciate it. Concerning the math itself, it is a bit above my pay grade at this point in my mathematical studies, but I will charge forward. Secondly, I misread the expression on the check. It looked like e^2*pi, not...

Good day all, I received this picture through the facebook network last night. I took it as valid at first sight, but for some reason it bothered me; in other words, my skepticism kicked in. The author mentions and assumes the limit as "n goes to infinity" which is annotated in the...

This is a great place to learn mathematics. :)

@ Keesjan... Thanks for the post the link to Armstrong Atlantic State University. Looks like there is a lot of good stuff posted. Plenty of information to digest. I'll definitely check them out. - Doc

Good morning, afternoon, and evening everyone! I used this website - http://www.aleks.com/ - for my VUB (Veterans Upward Bound) mathematics program this past summer. It has various prep subjects from elementary and high school math to prep courses for geometry, college algebra, trigonometry...

You're welcome, Georg. I'm glad it helped. It helped me to explain it. If you have any homework problems that your having trouble with, feel free to post them. I wouldn't mind taking a crack at them. I will do the same if your interested. - Doc

I like this site. This page also has the proof. And it's very understandable, at least I think. http://www.math.hmc.edu/calculus/tutorials/lhopital/

You can try this link: http://math.chapman.edu/~jipsen/mathposters/L%27Hospital%27s%20Rule.pdf I know why. f(a) = g(a) = 0 is just another way of saying f(x) = 0 = g(x). In other words, we want to use L'H's rule to help evaluate indeterminate forms like 0/0 and infinity/infinity. So would you...

Note: I haven't actually taken the time to go through my book's proof as of yet. But I have started my homework.

Same here. That's why I asked the question. My professor just covered L'Hopital's Rule today. This is what I got from my notes. First, we're going to use L'H's Rule to help evaluate indeterminate forms such as 0/0 and infinity/infinity. Note: If we don't have these forms, we can just use an...
