Your mistakes are at (i) Computing ||r_u x r_v (ii) Simplifying (x + y + z) as a function of you and v. ---- How to get the book's solution: r_u = and r_v = . R_u x r_v = .
R_u x r_v|| =?(49 + 25 + 9) =?83. So,? S (x + y + z) dS?
(u+v-1) + (u-2v) + (1-4u+v) * ||r_u x r_v|| dA?(v = 0 to 3)?(u = 0 to 2) -2u * (?83 du dv)?83?(v = 0 to 3) -u^2 {for you = 0 to 2} dv?83?(v = 0 to 3) -4 dv -12?83. I hope this helps!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
