Q1 (5 points) Let a-1)--)) [3 = [] = U = [(1a)] Compute the area of the parallelogram determined by four points with position vectors , v, +, 7. [(1b)] Compute the determinant of the 2 x 2 matrix [, ]. How do they compare? [(1c)] Replace the first entry of by an arbitrary number 3, and repeat the problem. [(10)] Draw a picture of both parallelograms and explain geometrically what happens to the area of the parallelogram when the first coordinate of is changed to 2
