To find the absolute value of the complex number, 3 + 4i, we find the distance from zero to that number on the complex plane.

Y = abs (X) returns the absolute value of each element in array X. If X is complex, abs (X) returns the complex magnitude. Examples collapse all Absolute Value of Scalar y = abs (-5) y = 5 Absolute Value of Vector Create a numeric vector of real values. x = [1.3 -3.56 8.23 -5 -0.01]' x = 5×1 1.3000 -3.5600 8.2300 -5.0000 -0.0100

The distance formula says the distance from the original to any point (x,y) is sqrt(x 2 + y 2), so the absolute value of 3+4i = sqrt(3 2 + 4 2) = 5. Notice that when you have a complex number with no imaginary part (such as 4+0i), the absolute value is the positive square root of the real part squared - in other words, the absolute value of the real part.

Complex numbers consist of real numbers and imaginary numbers. Hence, unlike integers, it is difficult to find the absolute value for them. Suppose, x+iy is the given complex number. z = x+iy. The absolute value of z will be; |z|= √ [Re (z) 2 +Im (z) 2 ] |z| = √ (x 2 +y 2) Where x and y are the real numbers.

The absolute value of complex number is also a measure of its distance from zero. However, instead of measuring this distance on the number line, a complex number's absolute value is measured on the complex number plane.

The absolute value of an imaginary number, a + bi, can be found using the following formula. |a+bi| =√a2+b2 | a + b i | = a 2 + b 2. For example,... See full answer below.

To find the absolute value of the complex number, 3 + 4i, we find the distance from zero to that number on the complex plane. As you might be able to tell, the final solution is basically the distance formula !

The absolute value of a complex number , a+bi (also called the modulus ) is defined as the distance between the origin (0,0) and the point (a,b) in the ...

The absolute value of a complex number a + bi, also called the modulus of a complex number a + bi, is its distance from the origin on the complex number plane.

Some complex numbers have absolute value 1. Of course, 1 is the absolute value of both 1 and –1, but it's also the absolute value of both i and – i since they're both one unit away from 0 on the imaginary axis. The unit circle is the circle of radius 1 centered at 0.

Notice that when you have a complex number with no imaginary part (such as 4+0i), the absolute value is the positive square root of the real part squared - in other words, the absolute value of the real part. So this "distance" method is just an extension of what you already use for real numbers. Hope this explanation helps, Stephen La Rocque. and,
