Document Summary

Problem 1 solution: find an equation of the plane passing through the following three points: p = (2, 1, 4), Q = (1, 1, 1), r = ( 4, 1, 1). Solution: let u = and v results in a vector normal to the plane containing p , q, and r. P q = h 1, 2, 5i and v = A plane containing a point (x0, y0, z0) with normal vector ha, b, ci has the equation. U v = h4, 27, 10i . a(x x0) + b(y y0) + c(z z0) = 0. Using p = (2, 1, 4) as a point in the plane we have. 4(x 2) + 27(y + 1) + 10(z 4) = 0. Problem 2 solution: let the position vector be given by r (t) = 2t3 + (t2 t) 8t k. Find the angle between the velocity and acceleration vectors at time t = 0.
