Example: Move the square root of 2 to the top: 13−√2 We can multiply both top and bottom by 3+√2 (the conjugate of 3−√2), which won't change the value of the fraction: 13−√2× 3+√23+√2 = 3+√232−(√2)2 = 3+√27 (The denominator becomes (a+b)(a−...

In other words, the modulus of a complex number is the square root of sum of the squares of real and imaginary part. The absolute value of the complex number z=x+ (split)|z|&=|x+|\&=√ (x^2+y^2)(split) Then, the square of the modulus of z is (split)|z|^2&=(√ (x^...
Let i be the square root of -1. Then, a typical complex number is written in the form a + bi where a and b are real numbers. In this case, a is the real part and bi is the imaginary part. Note that a can equal zero, so the complex number can just be of the form bi. ...
standard deviation(SD) the dispersion of a random variable; a measure of the amount by which each value deviates from the mean. It is equal to the square root of the variance. For data that have a normal distribution, about 68 per cent of the data points fall within (plus or minus) ...

The modulus of a complex number is the distance of the complex number from the origin in a complex plane. The modulus is also called as absolute value. In other words, the modulus of complex number is the square root of sum of the squares of real and imaginary part.The absolute value ...
Where the fourth line comes from the fact that ii is the square root of −1−1, so i2i2 is −1−1. So what do we get if we multiply zz by the conjugate? We get the square of the absolute value. Simple as that, no strings attached. It's what happens every time. The on...
