A complex number in polar form is written as z = r (cos + i sin ), where r is the modulus of the complex number and is its argument. Transcript. Notice that we ignore the signs of . So this number here, e to the j omega t, this is based on Euler's formula. The length or modulus of is written as The angle or argument is defined from the positive, real axis and is rotated anti-clockwise. However, as the absolute value of a complex number is simply the (Euclidean) distance from the origin to the number's position in the complex plane, we can use the Pythagorean theorem to calculate it. As consequences of the generalized Euler's formulae one gets easily the addition formulae of sine and cosine: For example 11+2i 25 = 11 25 + 2 25i In general, there is a trick for rewriting any ratio of complex numbers as a ratio with a real denominator.
