Part I - Vectors and Their Components v ha;bi x y x y jvj below.

Given a vector v = ha;bi, you can use the Pythagorean Theorem to nd its length and trigonometry to nd the angle it makes with the xor yaxes. Conversely, given the length of the vector and the angle it makes with the xor yaxes, you can write down its components. 1. Find the length jvjand the angle for the vector below. 2.
