Minimize the distance formula...
for the 1st one...
taking the derivative
setting equal to zero and solving for t gives the solution
Plug this back into the parametric equations to get the point...
Heres the question:
1. The point on the line x=-1+3t, y=-2+t, z=2-4t which is closest to the point (2,-2,2) is (_,_,_)? Fill in the blanks.
2. The point on the plane 3x+3y-2z=-2 that is closest to the point (1,-1,3) is (_,_,_)? again fill in the blanks
appreciate if anyone can help me on this fast since this question is due for me online in like 3 hours =S
