Glossary Entries
complex conjugate pairA complex conjugate pair is of the form $$a+bi, a-bi$$
complex numberA complex number is of the form $$a+bi$$, where $$a$$ and $$b$$ are real numbers. We call $$a$$ the real part and $$b$$ the imaginary part.
imaginary unitThe imaginary unit $$i$$ is the number whose square is $$–1$$. $$i^2 = -1$$ or $$i=\sqrt{-1}$$.
square of a numberIf $$n^2=m$$, then $$m$$ is the square of $$n$$.
square root of a numberIf $$n^2=m$$, then $$n$$ is a square root of $$m$$.
standard formA complex number is in standard form when written as $$a+bi$$, where $$a$$, $$b$$ are real numbers.
