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−...

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) ...

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^...
If z1 is a single real root of (3.31), then its additive contribution to the general solution of (3.30) is C1z1x. • Multiple real roots: If z1 is a multiple root with multiplicity index p, then its additive contribution to the general solution is (C1xp−1+C2xp−2+⋯+Cp)...
In the theory of probability the deviation (variance) of a random variableXis called the expected value E(X - mx)2of the square of the deviation ofXfrom its expected value mx=E(X). The deviation of a random variableXis denoted byD(X) or by σ2). The square root of the deviation ...
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 ...
