Document Summary

Spring 2017: (10 points) let u = h3, 1, 2i and v = h2, 0, 2i. Find the area of a parallelogram created by two vectors. Find a unit vector in the direction of a given vector. Find an orthogonal vector to a pair of vectors. Move the tip of one vector in the direc- tion of another vector. D: cross product: (8 points) the graph of the curve r (t) = (cid:10)4 2 cos(t), sin(2t)(cid:11) is shown below. Find, plot and label both the velocity and acceleration vectors at the time t = of the velocity and acceleration vectors are placed at the tip of the position vector. X2 : (6 points) let g(x, y, z) = ln(2y 3z + 4x). Your work must show the correct sequence of derivatives: (10 points) plot the three points (3, 0, 0), (0, 2, 0), and (0, 0, 4), then sketch the plane that contains them.
