Exer. 3962: Find the solutions of the equation that are in the interval [0, 2).

3.2 Algebraic Vectors Adding Vectors To add vectors, add corresponding components. Example: 24 6 When we add two vectors we’re finding the “resultant force”. A classic example: Consider a pin being pulled in two directions v u What the pin actually “feels” is the sum of the two vectors. v u+v u Example: Let A = (3, -1), B = (6 , 4), C = (3, 2) and D = (7,2). If " ! ! !!"! BA= =DC & (a) Find u + v. !!!" (b) Find K such that u+= !!" 6− 3 !!!" 73
