Definition that contains complex number
- imaginary part of a complex number the part of a complex number that has the square root of -1 as a factor
- modulus the absolute value of a complex number
- mandelbrot set a set of complex numbers that has a highly convoluted fractal boundary when plotted; the set of all points in the complex plane that are bounded under a certain mathematical iteration
- complex plane a geometric representation of the complex numbers established by the real axis and the orthogonal imaginary axis; it can be thought of as a modified Cartesian plane, with the real part of a complex number represented by a displacement along the x-axis, and the imaginary part by a displacement along the y-axis
- imaginary part the part of a complex number that has the square root of -1 as a factor
- complex conjugate either of two complex numbers whose real parts are identical and whose imaginary parts differ only in sign
