Complex Number System

... If is a + bi complex number, then it’s complex conjugate is a – bi. To form the conjugate of a complex number, simply negate the sign of the imaginary part of the complex number. One of the properties of the conjugate is that if you multiply a complex number by it’s conjugate, the result is a real n ...

... number i. Complex numbers are of the form a + bi : the real part is _a_ the imaginary part is _b_ The arithmetic of the complex numbers is much like the reals but there is the twist : i2 is always equal to -1, and you must always write the square root of a negative number as an imaginary number befo ...
