Copyright document.write(new Date().getFullYear()) KCK Media Corp.All Rights Reserved, https://circuitcellar.com/author/andrew-levido/. However, the naive tan 1 definition does obscure the fact that a complex number with negative real part and negative imaginary part lies in the 3rd quadrant: the range of t a n 1 is [ 2, + 2] which is only radians or 180 degrees wide - it covers only half of the phase space. z : When b=0, z is real, when a=0, we say that z is pure imaginary. To multiply complex numbers the imaginary number calculator use formula as: F * G = | z_1| * exp (i_1) * | z^2| * exp (i^2) = | z_1 * z^2| * exp (i(_1 + ^2)), we see: A * B = | z_1 * z^2| and arg (A * B) = _1 +^2. For example, the square root of 16 is 4 since 4 x 4 = 16. The calculator displays a stepwise solution of multiplication and other basic mathematical expressions. A complex number is a number in the form of a sum of a real part and an imaginary part a + bi.The symbol i or j in electrical engineering (electrical engineers think differently from the rest of the world!) The lines. Most loads in AC systems will have some resistive and some reactive component, so one number is not enough to describe power in these cases. Answer (1 of 2): According to Wikipedia [1], a complex number z can be written as: z = |z| e^{i \phi}\tag{1} Where: |z| is called the absolute value, modulus or magnitude \phi is called the argument or phase All you have to do is substitute the known values of |z|,\phi into (1).
