Study Notes

Finding a Vector Perpendicular to a Plane

  • The parametric equation of a plane is given by x = 3 + 1 s + 4 t, y = 2 + 3 s − 2 t, z = − 1 + 2 s + 3 t.
  • To find a vector perpendicular to the plane, we need to find two vectors that lie in the plane.
  • We can get these vectors by setting s=1 and t=0, and then setting s=0 and t=1.
  • These vectors are: [1, 3, 2] and [4, -2, 3].
  • The cross product of these two vectors will give us a vector that is perpendicular to the plane.
  • The cross product is calculated as follows: [1, 3, 2] × [4, -2, 3] = [13, 5, -14].
  • Therefore, [13, 5, -14] is a vector that is perpendicular to the plane.

Line-Plane Intersection

  • The line with parametric equations x = 1 + 1 t, y = 1 − t, z = 2 + t intersects the plane with equation x + 2 y + z − 10 = 0.
  • To find the point of intersection, substitute the parametric equations of the line into the equation of the plane.
  • This gives us: (1 + 1 t) + 2(1 − t) + (2 + t) − 10 = 0.
  • Simplifying the equation, we get 5 − t − 10 = 0.
  • Solving for t, we get t = -5.
  • Substitute this value of t back into the parametric equations of the line to find the point of intersection.
  • The point of intersection is (-4, 6, -3).
