  • Flux integrals, advanced engineering mathematics third edition, 9.13 #29

    This problem seems fairly straight-forward, but i keep getting 12, while the correct answer is 18. You end up evaluating the integral of 6yz with 0<z<2,0<y<sqrt(4-z^2), no?

  • help

    Two particles, Alpha and Beta, race form the y-axis to thevertical line x = 6π. Alpha's position is given by theparametric equations xα= (3t -3sint),yα = (3 - 3cost)and Beta's position is givenbyxβ= (3t - 4sint), yβ =(3 - 4cost) for t>=0. Which sentence best describes therace and its outcome?[a] Alpha moves slower and loses.[b] Alpha takes a shorter path and wins.[c] Beta starts out in the wrong direction and loses.[d] Beta moves faster but loses.[e] Alpha and Beta tie.

  • max and min of a triangle

    the level sets of F(x, y) are equally spaced parallel lines and F(0, 1) = F(1, 0) andFx(0,0) = 3. Let T be a triangle with vertices at the points (0, 0), (0, 2), and (1, 0). determine the points on the triangle where F has a maximum or minimum.
