Evaluate the surface integral S F · dS for the given vector field F and the oriented surface S. In other words, find the flux of F across S. For closed surfaces, use the positive (outward) orientation. F(x, y, z) = xy i + yz j + zx k S is the part of the paraboloid z = 2 − x2 − y2 that lies above the square 0 ≤ x ≤ 1, 0 ≤ y ≤ 1, and has upward orientation

In calculating the Pearson correlation coefficient, we assume that: a. the relationship we are trying to measure is curvilinear. b. the variables have been measured using interval- or ratio-scaled measures. c. the variables we want to analyze have a binomially distributed population. d. when the correlation coefficient is weak, there is a consistent, systematic relationship between the two variables. e. when the correlation coefficient is strong and significant, the two variables are associated in a curvilinear fashion.

Verify that the function u(x, y, z) = log x^2 + y^2 is a solution of the two dimensional Laplace equation u_xx + u_yy = 0 everywhere, except of course at the origin where f is not defined. Verify that the following functions solve the wave equation, u_tt = u_xx u(x, t) = cos(4x) cos(4t) u(x, t) = f(x - t) + f(x + 1), where f is any differentiable function of one variable.
