Question 01:
Sketch the vectors ro =< -1,2 > and v=< 1,1 > and then sketch the six vectors ro ±v,ro ± 2v,ro ±
3v. Draw the line L: –1+t,y = 2+ t, and describe the relationship between L and the vectors you have sketched.
What is the vector equation of L?
Question 02:
Let L, and L2 be the line whose parametric equations are:
L1:x = 4t, y = 1 – 2t, z = 2 + 2t
L2:x = 1+ t, y = 1 – t, z = -1+ 4t
• Show that L1 and L2 intersect at the point (2,0,3).
• Find, to the nearest degree, the acute angle between L1 and L2 at their intersection.
• Find parametric equations for the line that is perpendicular to L, and L2 and passes through their point of
intersection.
