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...

The route followed by a hiker consists of three displacement vectors A, B, and C. Vector A is along a measured trail and is 1550 m in a direction 25.0° north of east. Vector B is not along a measured trail, but the hiker uses a compass and knows that the direction is 41.0° east of south. Similarly, the direction of vector C is 35.0° north of west. The hiker ends up back where she started. Therefore, it follows that...
