• ### Stokes Theorem Help!?

Hello, I am having difficulty with the problem below. """ Use Stokes' Theorem to evaluate F · dr C is oriented counterclockwise as viewed from above. F(x, y, z) = xyi + yzj + zxk, C is the boundary of the part of the paraboloid z = 1 − x2 − y2 in the first octant. """ for curl F I got ( -y,-z,-x) and I... show more

""" for curl F I got ( -y,-z,-x) and I dotted that with the normal vector (2x, 2y, 1) Then I switched everything to polar coordinates to evaluate the double integral where theta is from 0 to pi/2 and r is from 0 to1. The answer I got was -43/60. I know this answer is wrong. Could someone help and explain a good way to approach a problem requiring stokes theorem? Thank you.

• ### 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!

• ### Python Help?

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.
