Glossary Entries
Word(s)	Definition	Image	Caption	Link	Source
complex conjugate pair	A complex conjugate pair is of the form $a + b i, a - b i$
complex number	A complex number is of the form $a + b i$ , where $a$ and $b$ are real numbers. We call $a$ the real part and $b$ the imaginary part.
complex number system	The complex number system is made up of both the real numbers and the imaginary numbers.
imaginary unit	The imaginary unit $i$ is the number whose square is $- 1$ . $i^{2} = - 1$ or $i = \sqrt{- 1}$ .
like radicals	Like radicals are radical expressions with the same index and the same radicand.
radical equation	An equation in which a variable is in the radicand of a radical expression is called a radical equation.
radical function	A radical function is a function that is defined by a radical expression.
rationalizing the denominator	Rationalizing the denominator is the process of converting a fraction with a radical in the denominator to an equivalent fraction whose denominator is an integer.
square of a number	If $n^{2} = m$ , then $m$ is the square of $n$ .
square root of a number	If $n^{2} = m$ , then $n$ is a square root of $m$ .
standard form	A complex number is in standard form when written as $a + b i$ , where $a$ , $b$ are real numbers.
