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 complex number is defined as a polynomial with real coefficients in the single indeterminate i, for which the relation i + 1 = 0 is imposed. … See more 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 $${\displaystyle i^{2}=-1}$$; … See more 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, … See more Equality Complex numbers have a similar definition of equality to real numbers; two complex numbers a1 + b1i … See more Construction as ordered pairs William Rowan Hamilton introduced the approach to define the set $${\displaystyle \mathbb {C} }$$ of complex numbers as the set See more 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 polynomials, it is common to write a for a + 0i and bi for 0 + bi. Moreover, when the … See more 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-dimensional space. The most immediate space is the Euclidean plane with suitable … See more 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 … See more WebThis is an interesting question.
