a, The vectors v1 = < 0, 2, 1 >, v2 = < 1, 1, 1 > , v3 = < 1, 2, 3 > , v4 = < -2, -4, 2 > and v5 = < 3, -2, 2 > generate R^3 (you can assume this). Find a subset of {v1, v2, v3, v4, v5} that forms a basis for R^3.

b. v1 = < 1, 0, 0 > , v2 = < 1, 1, 0 > and v3 = < 1, 1, 1 > is a basis for R^3 (you can assume this.) Given an arbitrary vector w = < a, b, c > write w as a linear combination of v1, v2, v3.

c. Find the dimension of the space spanned by x, x-1, x^2 - 1 in P2 (R).

Are the vectors v1 = (1 , 2, 3), v2 = (2, 4, 6), and v3...

Are the vectors v1 = (1 , 2, 3), v2 = (2, 4, 6), and v3 = (1, 1, 3) linearly independent or dependent? Since v2 is a scalar multiple of v1, both v1 and v2 are linearly dependent, but what does that say about the linear dependence of the three vectors as a whole?

if {v1,v2,v3} is a linearly independent set of vectors, then {v1,v2,v3,v4} is too.

(a) If V1,V2⊂V show that (V2^⊥)⊂(V1^⊥) implies V1⊂V2 (b) If V1,V2⊂V , show that (V1+V2)^⊥=(V1^⊥)∩(V2^⊥) where...

Java Write a method intersect_or_union_fcn() that gets vectors of type integer v1, v2, and v3 and determines if the vector v3 is the intersection or union of vectors v1 and v2. Example 1: If v1 = {2, 3, 1, 5}, v2 = {3, 4, 5} and v3 = {3, 5}, then: intersect_or_union_fcn(v1, v2, v3) will print: v3 is the intersection of v1 and v2 Example 2: If v1 = {2, 3, 1, 5}, v2 = {3, 4, 5}...
