Learning Objectives Implementing a Class Writing Constructors, Mutators and Accessors . Testing a Class Definition 1. A vector is defined as an element of a vector space. In the commonly used vector space R (Euclidean n-space), a vector is denoted by n coordinates and can be specified as T1,T2, ,Zn). Vectors are usu- ally referred to by the number of coordinates they have. A 2-dimensional vector x,x2) is may be referred to as a two-vector. More generally, an n-dimensional vector may be referred to as n-vector Binary operations such as addition, subtraction and multiplication by scalars are defined on vectors. Vector multiplication is not unique; different types of vector products, such as the dot product and cross product are defined as binary operations on vectors (z ), denoted Ilul. Definition 2. The vector norm of a two-vector u s equals to Vr* +y Definition 3. The unit vector of a two-vector u = (z,y), denoted u = = ). The norm of the unit vector is 1. The unit vector for the zero vector is undefined Definition 4. Two vectors in R2, U1 = Zi, y) and U2 = Zg's) are equal if and only if corresponding coordinates are equal, that is, = x2 and Adding Vectors in R2
