Complex numbers, despite the names, isn't really complicated. These are numbers which has an imaginary part and a real part. Complex numbers are expressed in the form {eq}x + iy {/eq}, where {eq}i {/eq} is equal to {eq}\sqrt {-1} {/eq}...
The principal value of a complex number {eq}z {/eq} is the value for {eq}\theta {/eq} that occurs within a predefined range of values, usually, but not always, {eq}(-\pi,\pi] {/eq}. The idea of the principal value is extended to areas in complex analysis where similar ...

Before moving to arithmetic operations on complex numbers, observe one more important relation between the cartesian and polar form of a complex number. You have seen how to write the polar form from the cartesian form. How do we do the reverse? This is quite straight forward: ...

The harmonic mean is calculated by dividing the number of observations, or entries in the series, by the reciprocal of each number. In contrast, the arithmetic mean is simply the sum of a series of numbers divided by the count of numbers in that series. The harmonic mean is equal to the...
Thearithmetic meanis 0.67%: the total of the returns divided by 10. However, the arithmetic mean of returns is only accurate when there is no volatility in the market. When the arithmetic mean of 0.67% is applied to each stock price, the end value is $152.63. However, the stock traded ...
