2.
a. Find the Euclidean distance between u → and v → and the cosine of the
angle between those vectors. State whether that angle is acute, obtuse,
or 90 °.
i. u → = (1,2,-3,0),
ii. u → = ( 0, 1,1,1,2), V→= (2,1, 0,-1, 3)
v→=(5,1,
= (5,1,2,-2)
→=
b. Verify that the Cauchy-Schwarz inequality holds.
i. u (4,1,1), V→=(1,2,3)
ii. u → = ( 1, 2,1,2,3), v→ = (0,1,1,5,-2)
