Noun1.complex conjugate- either of two complex numbers whose real parts are identical and whose imaginary parts differ only in sign complex number,complex quantity,imaginary,imaginary number- (mathematics) a number of the form a+bi where a and b are real numbers and i is the square root of...
Now find modulus of z. The modulus of a complex number is the distance of the complex numbefrom the origin in a complex plane. The modulus is also called as absolute value. In other words, the modulus of a complex number is the square root of sum of the squares of real and ...
It can help us move a square root from the bottom of a fraction (the denominator) to the top, or vice versa. Read Rationalizing the Denominator to find out more:Example: Move the square root of 2 to the top: 13−√2 We can multiply both top and bottom by 3+√2 (the conjugate ...

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. ...
Wherever they appear, one thing is certain: the square root of a negative number doesn't exist… Or does it?The origin of complex numbers Complex numbers are of the form z=a+biz=a+bi, where aa and bb are real numbers (i.e., any of the numbers that we learned about in school),...
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 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 ...
