Lecture 6 *Tues. Sept. 24*

Review exercises in preparation for Exam1 this Thrs.
Recall only Maple and Chap10 are included. Don't forget to bring a number 2 pencil and your SUNYA ID.
  • Find the line of intersection of the planes:
    y - x - z = 1
    x + y - z = -1
  • Find the angle that
    v= 2 i + j
    makes with (-1,1,1), (1,0,1), (-2,2,1).
  • Do the vectors:
    i + 2k -j, i + j - k, 3i + j
    lie on a plane?
  • Compute the area of the triangle PQR where:
    P(0,1,0), Q(2,1,0), R(1,0,1)
  • Find the symmetric equations of the line through the origin perpendicular to the plane:
    z - x - y = 5
  • Consider the line:
    x = -3t - 1
    y = 2t - 2
    z = t - 1
    and the plane: x + y + z = 3. Do the line and the plane intersect? You may be able to look at both the line and the plane with maple:

    > line:=plot3d([-3*t-1,2*t-2,t-1], t=-5..5,s=0..1,grid=[2,2]):

    > plane:=plot3d(3-x-y,x=-3..3, y=-3..3,orientation=[103,110]):

    > with(plots): display3d({line,plane});
