Prevedi complex number na: nemački

A number of the form a + bi, where a and b are real numbers and i is the square root of -1, called the imaginary unit. Complex numbers can be plotted as points on a two-dimensional plane called the complex plane. The a number is plotted along the plane’s horizontal axis (the real axis), and the b number is plotted along the vertical axis (the imaginary axis). Compare real number.
A number of the form a+bi where a and b are real numbers and i is the square root of -1; SYN. complex quantity, imaginary number.
In mathematics, a number written in the form a + ib, where a and b are real numbers and i is the square root of -1 (that is, i2 = -1); i used to be known as the “imaginary” part of the complex number. Some equations in algebra, such as those of the form x2 + 5 = 0, cannot be solved without recourse to complex numbers, because the real numbers do not include square roots of negative numbers.
The sum of two or more complex numbers is obtained by adding separately their real and imaginary parts, for example:
(a + bi) + (c + di) = (a + c) + (b + d)i Complex numbers can be represented graphically on an Argand diagram, which uses rectangular Cartesian coordinates in which the x-axis represents the real part of the number and the y-axis the imaginary part. Thus the number z = a + bi is plotted as the point (a, b). Complex numbers have applications in various areas of science, such as the theory of alternating currents in electricity.
