Quantities that have magnitude and direction but not position. Some examples of vectors are velocity, displacement, acceleration, and force. They are sometimes called Euclidean or spatial vectors.
This question is regarding vectors and matrices, what do I match these 4 parts with when the 5 choices to match with are:
It equals 1
It is meaningless
It equals 0
It equals 4
It equals the zero vector
deal with the problem of solving Ax = b when det A = 0.22.Suppose that, for a given matrix A, there is a nonzero vector x such that Ax = 0. Show that there is also a nonzero vector y such that A*y = 0.
The objective of this problem is to write a polynomial p(x) = a + bx + cx2 in the form of p(x) = k1 +k2(1−x)+k3(1−2x)(1−3x).
(a) Describe how would you construct a matrix for this purpose. Use E = {1, x, x2}.
(b) Write p1(x) = 1 − 2x + 3x^2 in the desired form.
(c) Write p2(x) = 3 + 2x − 5x2 in the desired form.
