Chapter 1 Vector Algebra
1. Let u.. =(1, 2, 0) and v.. =(3,.4, 0). Compute u.. +v.. , u.. .v.. , 2u.. +12v.. , and .2u..+v..
and draw the vectors relative to a coordinate system.
u.. +v.. =(1, 2, 0)+(3, .4, 0)= (1+3, 2+(.4), 0+0) = (4, .2, 0)
u.. .v.. =(1, 2, 0).(3, .4, 0)= (1.3, 2.(.4), 0.0) = (.2, 6,0)
2u..+1 2v..= 2(1, 2, 0)+1 2(3,.4, 0)=(2+3 2, 4+(.2), 0+0)=(7 2, 2,0)
.2u..+v.. = .2(1,2,0)+(3,.4,0)=(.2+3,.4+(.4),0+…
