Question 1

Find the value of the positive constant real number k such that the function is harmonic for all points in 3-space.
◦ 2 -
◦ 3
◦ 2 +

◦ 2

Question 2

Compute fxx(x, y)  and fyy(x, y)  if  f(x, y) = xy + sin xy + x2 + 5xln y.
◦ fxx(x, y)  =  y2 sin xy + 2,  fyy(x, y) = - x2 sin xy -
◦ fxx(x, y)  = - y2 sin xy + 2,  fyy(x, y) =  x2 sin xy -
◦ fxx(x, y)  = - y2 sin xy + 2,  fyy(x, y) = - x2 sin xy +
◦ fxx(x, y)  = - y2 sin xy + 2,  fyy(x, y) = - x2 sin xy -
◦ fxx(x, y)  = - x2 sin xy + 2,  fyy(x, y) = - y2 sin xy -
