1. Given 3 points: A(2, 3, 5), B(5, 1, 2) C(-2, -3, 4)
(a) Plot and label the points.
(b) Graph, label, and give the component form for vectors u = BA and v = BC
(c) Use the dot product to compute the angle between the vectors; round your answer to the nearest degree.
(d) Use the cross product to determine the equation of the plane containing the 3 points.
