Consider the two points PIII, 1,4} and Q{4,, 5} and the vector 3 v= o [t ~'r'ou are given that _, 3 Po: 1 1 Let I he the straight line in H3 through the point P parallel to the Iilector 1:. Calculate the quantities below and enter them in the boxes provided using Maple notation. Remember to give exact answers using Maple notation. For example, for 21,!th enter 2 *5qrt: {41'} and for the 1 vector 2 enter {1, 2, 3). 3 > _ > ' The projection of PG onto 1r is the vector proijQ = I loo The shortest distance between the line t? and the point Q is I I n l
