amplitude(`1+i`), returns `pi/4`

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

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.

amplitude(complex), complex is a complex number.
