Complex numbers allow solutions to all polynomial equations, even those that have no solutions in real numbers. More precisely, the fundamental theorem of algebra asserts that every non-constant polynomial equation with real or complex coefficients has a solution which is a complex number.
The complex numbers with integer part all zeroes in the base i – 1 system Of particular interest are the quater-imaginary base (base 2 i ) and the base −1 ± i systems discussed below, both of which can be used to finitely represent the Gaussian integers without sign.
In mathematics, the complex conjugate of a complex number is the number with an equal real part and an imaginary part equal in magnitude but opposite in sign. That is, if a {\displaystyle a} and b {\displaystyle b} are real numbers, then the complex conjugate of a + b i {\displaystyle a+bi} is a − b i . {\displaystyle a-bi.}
LaTeX can be used from within Euler to display formulas. For export of formulas to HTML, either the generated LaTeX images or MathJax can be used. A special export option exports all graphics to SVG. Euler also includes the Tiny C Compiler, which allows subroutines in C to be compiled, and included via a Windows DLL.
x is the argument of the complex number (angle between line to point and x-axis in polar form). The notation is less commonly used in mathematics than Euler's formula, e ix, which offers an even shorter notation for cos x + i sin x, but cis(x) is widely used as a name for this function in software libraries.

In fact, the same proof shows that Euler's formula is even valid for all complex numbers x. A point in the complex plane can be represented by a complex number written in cartesian coordinates. Euler's formula provides a means of conversion between cartesian coordinates and polar coordinates. The polar form simplifies the mathematics when used ...
