COMPLEX NUMBERS - NUMBER THEORY
COMPLEX NUMBERS 5.1 Constructing the complex numbers One way of introducing the field C of complex numbers is via the arithmetic of 2×2 matrices. DEFINITION 5.1.1 A complex number is a matrix of the form x −y y x , where x and y are real numbers. Complex numbers of the form x 0 0 x are scalar matrices and are called

COMPLEX ANALYSIS - UNAM
www.matem.unam.mxTwo complex numbers are equal if and only if they have the same real part and the same imaginary part. Addition and multiplication do not lead out from the system of complex numbers. Assuming that the ordinary rules of arithmetic apply to complex numbers we find indeed (1) (a + i(:3) + ('Y + ifi) = (a + 'Y) + i((:3 + fi) and

Since x is negative, the length of the horizontal side is x. Thus, tan(p q) = y=( x), and, since tan 1 is an odd function, it follows that q =p+tan 1(y=x). Since
