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 $| z | = \sqrt{a ^ 2 + b ^ 2}$. Notice that if $$z$$ is a real number (i.e. Derivative of a function | Let z = a + ib be a complex number.

Calculate Taylor expansion online | Solve system | scalar product calculator |, Graphing calculator | Factorization | Modulus of a Complex Number Description Determine the modulus of a complex number . $$z = a + 0i$$) then, 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). Solve | Antiderivative calculator | Instructions:: All Functions. Sometimes this function is designated as atan2(a,b). Calculus software online | Expand math | permutation calculator | The complex_modulus function allows to calculate online the complex modulus. Let $$Z$$ be a complex number given in standard form by$$Z = a + i$$The modulus $$|Z|$$ of the complex number $$Z$$ is given by$$|Z| = \sqrt {a^2 + b^2}$$and the argument of the complex number $$Z$$ is angle $$\theta$$ in standard position.eval(ez_write_tag([[728,90],'analyzemath_com-medrectangle-3','ezslot_3',320,'0','0']));Note Since the above trigonometric equation has an infinite number of solutions (since $$\tan$$ function is periodic), there are two major conventions adopted for the rannge of $$\theta$$ and let us call them conventions 1 and 2 for simplicity.Convention (1) define the argumnet $$\theta$$ in the range: $$0 \le \theta \lt 2\pi$$Convention (2) defines the argument $$\theta$$ in the range : $$(-\pi, +\pi ]$$The four quadrants , as defined in trigonometry, are determined by the signs of $$a$$ and $$b$$If the terminal side of $$Z$$ is in quadrant (I) or (II) the two conventions give the same value of $$\theta$$.If the terminal side of $$Z$$ is in quadrant (III) or (IV) convention one gives a positive angle and covention (2) gives a negative angle related by$$\theta_{\text{convention 2}} = \theta_{\text{convention 1}} - 2\pi$$This calculator calculates $$\theta$$ for both conventions.
