# What is the modulus of complex number?

Modulus of a Complex Number. Definition of Modulus of a Complex Number: Let z = x + iy where x and y are real and i = √-1. Then the non negative square root of (x2+ y 2) is called the modulus or absolute value of z (or x + iy).

Also, what is the modulus and argument of a complex number?

The modulus can be found by using Pythagoras' Theorem where a complex number in the form z=a+bi has a modulus of sqrt(a^2+b^2). The argument of a complex number is the angle between the positive real axis and the line segment created by the complex number and the origin in the anticlockwise direction.

One may also ask, what is the modulus of a number? The modulus of a number is its absolute size. That is, we disregard any sign it might have. Example The modulus of −8 is simply 8. The modulus of 0 is 0. So, the modulus of a positive number is simply the number.

People also ask, what is the complex modulus?

Dynamic modulus (sometimes complex modulus) is the ratio of stress to strain under vibratory conditions (calculated from data obtained from either free or forced vibration tests, in shear, compression, or elongation). It is a property of viscoelastic materials.

Is the modulus of a complex number always positive?

Modulus. Notice that the modulus of a complex number is always a real number and in fact it will never be negative since square roots always return a positive number or zero depending on what is under the radical.
