Let the four compass directions north, east, south, and west be represented by unit vectors ne . . and respectively. Vertically up and down are represented as u and d. Let us also identify unit vectors that are halfway between these directions such as for northeast. Rank the magnitudes of the following cross products from largest to smallest. If any are equal in magnitude or are equal to zero, show that in your ranking, (a) (b) (c) (d) (e)

1. You are trying to find your family's hidden treasure by your ancestor using a map. The map says that starting from your house, first, you need to walk 3.00m, East. After that, you again walk 3.00m, 60O N of E. Then go 2.00m North. And finally move 4.00m, 300 S of W. If the treasure's location is the resultant vector. Find the magnitude and direction of the treasure. (Use component method)
