WebComplex Numbers as Vectors in the Complex Plane. A complex number z= x+iy can be identi ed as a point P(x;y) in the xy-plane, and thus can be viewed as a vector OP in the plane. All the rules for the geometry of the vectors can be recast in terms of complex numbers. For example, let w= s+ itbe another complex number. Then the point for Web§1.2 Recap on complex numbers A complex number is an expression of the form√ x+ iywhere x,y∈ R. (Here idenotes −1 so that i2 = −1.) We denote the set of complex numbers by C. We can represent C as the Argand diagram or complex plane by drawing the point x+iy∈ Cas the point with co-ordinates (x,y) in the plane R2 (see Figure 1.2.1). album cientifico

WebComplex Numbers The imaginary number i = √ −1 is an extension to the real number system which allows us to solve equations such as x2 = −1. A complex number is any number of the form z = a+bi, where a and b are real numbers. Note: All numbers involving i can be written in this form. Examples: (a) i2 +i3 (b) 2i−3 i+1 = −1+i2i = 2i−3 ...
