2. Linear dependence of vectors: If we want to describe any vector in three dimensions, we need a basis of three vectors, and we usually choose i,j. k, the unit vectors in the r, y, z directions. We could equally well have chosen for example a = i+5, b = i-j and c = i+2] _ k. Then the vector v = 41+2] _ k would be expressed as v = 3a + )b-c a, b, c form a suitable...

1. Given the vectors ū=(1,-2,-6) and v = (0,-3,4), a) Find u 6v. b) Find a unit vector in the opposite direction to ū. c) Find (ü.v)v. d) Find 11: e) Find the distance between ū and v. f) Are ū and y parallel, perpendicular, or neither? Explain. g) Verify the Triangle Inequality for ū and ū.
We will continue to work on the concepts of basis and dimensions in this homework Again, if necessary, you can use your calculator to compute the rref of a matrix 1 (5 points) Recalled that in Calculus, if the dot product of two vectors is zero, then we know that the two vectors are orthogonal (perpendicular) to each other. That is, if yi 3 y3 then the angle between the two vectors is coS 2 The two vectors z and...
Exercise 1. Let v = 2 ER3. Recall that the transposed vector u is ū written in row form, 3 that is, of = [1 2 3]. It can be seen as a 1 x 3 matrix. For every vector R3, set f(w) = 1 WER. (i) Show that f: R3 → R defines a linear transformation. (ii) Show that f(ū) > 0. (iii) What are the vectors we R3 such that f(w) = 0?
Let u and v be the vectors shown in the figure to the right, and suppose u and v are eigenvectors of a 2 x2 matrix A that correspond to eigenvalues -2 and 3, respectively. Let T: R2 R2 be the linear transformation given by T(x)-Ax for each x in R2, and let w-u+v. Plot the vectors T(u), T(v), and T(w). 2- u -2 2 4 -2 10- T(v) T(w -10 10 T(u) -10- Ay 10- T(v) T(w) T(u) 10...
