There will be a review session for the test on Wednesday, 20 February at 7:30 p.m. in 4-163. 1. (a) Find the area of the triangle with vertices P 1 = (2 , 1 , 0), P 2 = (1 , 1 , 1), and P 3 = (0 ,- 1 , 3). (b) Find the equation of the plane containing the points P 1 , P 2 , and P 3 . (c) Find the point where the line through Q 1 = (- 2 , 1 , 3) and Q 2 = (0 ,- 3 , 1) intersects the plane found in (b). 2. Find all the values of c for which the planes 2 x- y + z = 0 4 x- 2 y + z = 0 cx + y = 1 meet in a unique point. 3. (a) Find the point of intersection of the three planes 2 x + y- 2 z = 1 x- y- z = 3 x + 2 y + z = 2 by writing the equations above as a linear system...
