Synopsis

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In mathematics, the real and imaginary parts of a complex number z are respectively the first and the second elements of the ordered pair of real numbers representing z. If z = x + iy (with i denoting the imaginary unit), then x and y are respectively the real part and the imaginary part of z. The real part of a complex number z is denoted by Re(z) or ¿(z) and the imaginary part by Im(z) or ¿(z), where ¿ and ¿ are black-letter capital R and I, respectively. The notations without parentheses are also used, Re¿z or ¿¿z and Im¿z or ¿¿z, whenever there is no danger of ambiguity. For a complex number in polar form, z = (r,¿), the Cartesian (rectangular) coordinates are z = (rcos¿,rsin¿), or equivalently.
