An imaginary number is of the form, <math>\theta i</math>, where <math>\theta</math> is a [[real number]].
An imaginary number is of the form, <math>\theta i</math>, where <math>\theta</math> is a [[real number]].
For example <math>\sqrt{-1}</math> has imaginary solution of,
For example <math>\sqrt{-1}</math> has imaginary solution of
:<math>\sqrt{-1}=\pm i</math>.
:<math>\sqrt{-1}=\pm i</math>.
When a imaginary number is added to real-number, they form a [[complex number]].
When a imaginary number is added to real number, they form a [[complex number]].
