  • Triple Integral Conceptual Question?

    Both double and triple integrals find volume, right? How does f(x,y,z) have volume if one needs four dimensions to graph it? For example, how would f(x,y,z) = x^2 + y^2 + z^2 have volume? Wouldn't you need four dimensions to graph it in, since it would essentially be w = x^2 + y^2 + z^2? Thank you in advanced!

    A quick question about lists. list = [3,4,5,7,5,6] In the list above the number 5 is in the list twice. How could one go through the list, testing for duplicate numbers, and add 0.01 to one number that is a duplicate while leaving the other unchanged. For example: list = [3,4,5.01,7, 5,6] Thank you.

However it just prints out * , * , * ect. Any help would be appreciated, I have really just begun coding so its probably something simple. Thanks in advanced! There are indents in the actual code, they just did not show up on yahoo for some reason.

    I agreed to a trade with someone, exchanging basketball cards. We haven't exchanged the cards yet, but only now am I realizing how much I am being jacked. We agreed to trade some autographed cards. I thought the value for each card was around the 15-20 dollar range (Klay Thompson, Andre Iguodala). However to my surprise the certain Klay Thompson signed card, that I had, was selling online for upwards of 25 dollars. Meanwhile the Iguodala was only selling for about 6 dollars. Should I back out, or honor the commitment. Any help would be appreciated. Normally I would just go through with it, but in this case this is about a twenty dollar difference. I suspect that the person that I trade with knew that it was a bad deal for me, because he accepted eagerly.
