Solution

1)For all u, v E R^3, we have u . (u x v) = 0
Solution: True. As angle between u and
(u x v)= 90 degree.
2)For all vectors x, y E R^2, we have proj x = proj y? (x and y have a right arrow on top of
them)
Solution: False. If x and y are two different vectors then it may not be true.
3)If there are more variables than equations in a system of linear equations, then there can
NOT be a unique solution to the system?...
