Find v(t), Iv(t)1 and T(t). 4) Let p = (0,2,3) and consider the plane 7[ given by x + y 2z = 4. a) (8 points) Find the equation of a line through p perpendicular to 7[ . b) (7 points) Find the point Q of intersection of this line with 7[ . c) (7 points) Find the distance from p to 7[ , that is the distance from p to Q Find the domain and range of f. Is the domain 5) a) (8 points) Let J(x, y) = In(l + xy) open, closed, bounded? b) (7 points) Does lim :: exist? (x,y)+(O,O) y 6) (10 points) Say u and v are vectors such that lul > O and I vi > O u x v = v x u. What can you say about the angle between u and v? Suppose also that...
