Re: I need help

[agentcthulhu]

Uh, I just realized I should have used subscripts to denote upper and lower bounds. What if I write it like this?

X_upper = 9 (((X_upper is a variation of the variable X I'm using to denotes the upper bound of X. Don't use superscripts like ' or " - which I did, which is BAD! - or any superscripted numbers. Use a subscript number or letter instead!)))

U = X² + 3X - 1
(((Rewrite using U_upper and X_upper so I'm clear which number I want to substitue in and other people can see why I used the numbers I did)))
U_upper = (X_upper)² + 3*(X_upper) - 1
U_upper = (9)^2 + 3*(9) - 1
U_upper = 81 + 27 - 1 = 107

Therefore the upper bound of U is 107.

Better?

Yes! I thought you were taking the derivatives of x, and I was slightly confused. ^^;

Yeah, sorry, that was completely my fault. If only I can erase my previous comment and substitute it with the clearer version. Brain fart, my bad!

If you've any more questions about u-substitution or other aspects of calculs, please don't feel too shy to ask! I'm sure someone will answer your questions. If not, I'll take a look - if you don't mind some waiting! (I have to be asleep in 30 minutes and I probably won't be back until after 0100 UTC May 9, 2013.) Though I will be check back on this thread for the next 3 days or so. :)

I think I'm good on this thread, but I will post in other GC comments in the future! You all explained things a lot more clearly then my teachers did. (To be fair, they have so many students, and so much material to get through.)

Re: I need help

[agentcthulhu]

Too many students at different knowledge levels is an issue that teachers can't solve easily. Sometimes it isn't really the teacher being at fault because they are so used to students not understanding a topic they're talking about NOW, they forget it might be a much more basic concept that's causing students problems. You can try fixing the 11th wheel in the machine as much as you want, but the machine won't work if the 1st wheel is missing! (I don't know if this analogy works, haha...)

Good luck!
