Imaginary unit i is used to represent the square root of a negative number, where i equals the square root of -1.
Complex numbers are in standard form a + bi, where a and b are real numbers.
To be considered a complex number, the expression must be in the exact form a + bi. Examples of complex numbers in standard form:
When raising i to various powers, follow this simple pattern:
Complex numbers cannot be in the denominator, so in order to get it into the top, multiply the whole fraction be the conjugate (a - bi).
That seems to be about it for imaginary and complex numbers!
