Similarly, if we consider = + to represent the vector A = , on the Argand diagram, we see that | … If $z = a + bi$ is a complex number, then we can plot $z$ in the plane as shown in Figure $\PageIndex{1}$. How to calculate the modulus of a real number. Example: Take $ z = 1+i $, the real part is $ 1 $, the imaginary part is $ 1 $ and the modulus of the complex number $ |z| $ equals $ \sqrt(2) $, so $ \arg(z) = 2 \arctan \left( \frac{1}{1 + \sqrt(2) } \right) = \frac{\pi}{4} $ The result of the $ \arg(z) $ calculation is a value between $ -\pi $ and $ +\pi $ and the theta value is modulo $ 2\pi $ As imaginary unit use i or j (in electrical engineering), which satisfies basic equation i 2 = −1 or j 2 = −1.The calculator also converts a complex number into angle notation (phasor notation), exponential, or polar coordinates (magnitude and angle). Complex Numbers Calculator. For the complex numbers $ z, z_1, z_2 $ the complex modulus has the following properties: $$ |z_1 \cdot z_2| = |z_1| \cdot |z_2| $$, $$ \left| \frac{z_1}{z_2} \right| = \frac{|z_1|}{|z_2|} \quad z_2 \ne 0 $$. The behaviour of arithmetic operations can be grasped more easily by considering the geometric equivalents in the complex plane. Example: Take $ z = 1+i $, the real part is $ 1 $, the imaginary part is $ 1 $ and the modulus of the complex number $ |z| $ equals $ \sqrt(2) $, so $ \arg(z) = 2 \arctan \left( \frac{1}{1 + \sqrt(2) } \right) = \frac{\pi}{4} $ The result of the $ \arg(z) $ calculation is a value between $ -\pi $ and $ +\pi $ and the theta value is modulo $ 2\pi $ The argument of a complex number is the direction of the number from the origin or the angle to the real axis. An alternative option for coordinates in the complex plane is the polar coordinate system that uses the distance of the point z from the origin (O), and the angle subtended between the positive real axis and the line segment Oz in a counterclockwise sense. Very simple, see examples: ,$\color{blue}{\text{ 2r3 } = 2\sqrt{3}} $ By decomposing the number inside the radical, we get = √(5 ⋅ 5) = √5. Modulus of Complex Number Calculator.

Example 5 : The Modulo Calculator is used to perform the modulo operation on numbers. To find the module of a complex number $ z = a + ib $ carry out the computation $ |z| = \sqrt {a^2 + b^2} $ Example: $ z = 1+2i $ (of abscissa 1 and of ordinate 2 on the complex plane) then the modulus equals $ |z| = \sqrt{1^2+2^2} = \sqrt{5} $ About Modulo Calculator . This gives us a general formula for the modulus of a complex number, a+ bi. The modulus (or magnitude) is the length (absolute value) in the complex plane, qualifying the complex number $ z = a + ib $ (with $ a $ the real part and $ b $ the imaginary part), it is denoted $ | z | $ and is equal to $ | z | = \sqrt{a ^ 2 + b ^ 2} $. The module can be interpreted as the distance separating the point (representing the complex number) from the origin of the reference of the complex plane.
