Complex number multiplication is the process of multiplying two or more complex numbers using the distributive property. If we have two complex numbers, z = a + ib and w = c + id, then multiplication of z and w is written as zw = (a + ib) (c + id). To find the product of com...
Complex numbers: Algebra - Alpay - 2011 () Citation Context ...A complex number can be used to encode information—it is a number that can be put in the form x = xR + xI, (1) where xR is the real component and xI is the imaginary component of the complex number x =-=[2, 3...

The square root of any negative number can be written as a multiple of ii. To plot a complex number, we use two number lines, crossed to form the complex plane. The horizontal axis is the real axis, and the vertical axis is the imaginary axis. Complex numbers can be added and subtract...
is not a real number. We call it a complex or imaginary number.Thus symbols such as , , , and so on—the square roots of negative numbers—we will now call complex numbers. Our knowledge of a complex number is, when squared, produces the radicand. , when squared, produces −3. ...

Clifford algebra provides a systematic framework for generalizing the known algebras of complex numbers and quaternions to any number of dimensions. For a more comprehensive discussion of its methods and diverse applications in science and engineering, see [30, 133, 134, 238, 310]. 展开 ...
refer to √a as the principal square root (主平方根) of nonnegative real number a. A number that is the square of a rational number is called a perfect square(完全平方),such as 16, 4/9. A number that is the nth power of a rational number is called a perfect nth power(完全n次方...
