### Amplitude, online calculus

#### Summary :

The amplitude calculator determines the amplitude of a complex number from its algebraic form.

amplitude online

#### Description :

The plan has a direct orthogonal reference (O,vec(i),vec(j)). Lets z a non zero complex number and M its image. Called amplitude of z, any measurement, expressed in radians, of the angle (vec(i),vec(OM))

The amplitude function allows to calculate the amplitude of a complex number online.

To calculate the amplitude of a complex number, just enter the complex number and apply the amplitude function amplitude. Thus, for calculating the argument of the complex number following i, type amplitude(i) or directly i, if the amplitude button appears already, the amplitude pi/2 is returned.

#### Syntax :

amplitude(complex), complex is a complex number.

#### Examples :

amplitude(1+i), returns pi/4
