Problem 21DQ

Let represent any nonzero vector. Why is a unit vector, and what is its direction? If ? is the angle thamakes with the + x -axis, explain why is called the direction cosine for that axis.

Step-by-Step Solution:

Solution to 21DQ Here in the first part of the solution we would enquire about Unit Vector and its direction.In the second part we would see why(A) .i is a direction cosine in that axis. PART 1 Step 1. Mathematically a vector is defined as a dot product of its magnitude and its direction. =|A|.A Here A t he component that gives the direction of the vecto. he magnitude is given by | |
