Lao Bi's home in California is full of mosquitoes.
While Lao Bi was writing this exam, a nasty mosquito bit Lao Bi in the arm. The mosquito then
escaped before Lao Bi could swat it, flying in a spiral pattern about Lao Bi with a trajectory given,
in polar coordinates, by r(1) = Ke and A(r) = ct, where K> 0 and c > 0 are both constants.
Find the angle, W(1), between the velocity vector and the acceleration vector for this annoying mosquito.
