Illustrate the difference a b graphically a i 4j b 3i 3

Illustrate the difference a ? b graphically. a = ?i + 4j; b = ?3i + 3j please explain your answer

Illustrate the difference a ? b graphically. a = -i + 4j; b = -3i + 3j please explain your answer

Solution

An easy way to approach this problem is actually solving the problem a - b is same as (-i+4j) - (-3i+3j) which is equal to (2i+j). Recall i is in the x-direction, and j is in the y-direction, so you\'re looking for a vector 2 at x, and 1 at y. Which of these graphs have that resulting vector? Final answer: 2)
