Question
Project the vector
b = (1,3,1)" onto the line
through
%3D
a, %3D (-1,2, 2)Т,
az = (2, 2, –1)",
аз3 (2, —1,2)Т.
Answer the following questions:
1) Find the three projection
vectors p1, p2 and p3.
2) Find the projection matrices
P1, P2 and P3.
3) Verify that P1+P2+P3=I.
Therefore the three vectors
a1, az and az
are
perpendicular to each other.
