Show that the set S = {(1, 3, -4, 2)T, (2, 2, -4, 0)T, (1, -3, 2, -4)T, (-1, 0, 1, 0)T} in ℝ4 is linearly dependent by verifying that r = 4, s = -3, t = 2, w = 0 satisfies the definition.

Why are VECTORS important?

"VECTOR, 1. A variable quantity that can be resolved into components. 2. A straight line segment whose length is magnitude and whose orientation in space is direction. (Princeton WordNet Database, as used in WordWeb Dictionary.) Can you exemplify the difinition and make it more useful to me, thank you!"

(Every direction is a vector) Let "N hat"

represent the direction horizontally north, "N E hat"

represent northeast (halfway between north and east), and so on. Each direction specification can be thought of as a unit vector. Rank from the largest to the smallest the following dot products. Note that zero is larger than a negative number. If two quantities are equal, display that fact in your ranking. (Use only ">" or "=" symbols. Do not include any parentheses around the letters or symbols.) (a) "N hat dot N hat"

How do you write unit vectors for these vectors.? Physics homework.?

"How do you write unit vectors for these vectors.? Physics homework. Take a look here: http://i303.photobucket.com/albums/nn129/wvmounti31/YF-01-48.jpg 1) Write the vector B in the figure in terms of the unit vectors i(hat) and j(hat) . 2) Use unit vectors to express the vector C, where C= 3.00 A- 4.00B . 3) Find the magnitude of C. 4) Find the direction of C. Thanks!"
