Origin of complex numbers
The impetus to study complex numbers as a topic in itself first arose in the 16th century when algebraic solutions for the roots of cubic and quartic polynomials were discovered by Italian mathematicians (see Niccolò Fontana Tartaglia, Gerolamo Cardano ). Zobacz więcej In mathematics, a complex number is an element of a number system that extends the real numbers with a specific element denoted i, called the imaginary unit and satisfying the equation $${\displaystyle i^{2}=-1}$$; … Zobacz więcej A complex number z can thus be identified with an ordered pair $${\displaystyle (\Re (z),\Im (z))}$$ of real numbers, which in turn may be interpreted as coordinates of a point in a two … Zobacz więcej Equality Complex numbers have a similar definition of equality to real numbers; two complex numbers a1 + … Zobacz więcej A complex number is a number of the form a + bi, where a and b are real numbers, and i is an indeterminate satisfying i = −1. For example, 2 + 3i is a complex number. This way, a … Zobacz więcej A real number a can be regarded as a complex number a + 0i, whose imaginary part is 0. A purely imaginary number bi is a complex number 0 + bi, whose real part is zero. As with … Zobacz więcej The solution in radicals (without trigonometric functions) of a general cubic equation, when all three of its roots are real numbers, contains the square roots of negative numbers, … Zobacz więcej Field structure The set $${\displaystyle \mathbb {C} }$$ of complex numbers is a field. Briefly, this means that the following facts hold: first, any two complex numbers can be added and multiplied to yield another complex number. … Zobacz więcej WitrynaThis rather famous quote by nineteenth-century German mathematician Leopold Kronecker sets the stage for this section on the polar form of a complex number.
