Problems solving in electrical engineering — algebraic and indicative recording form of values for the complex amplitude method

The complex amplitude is such value, which module and argument are equal, respectively, to amplitude and phase of the harmonic (sinusoidal) signal.

Suppose that there is a signal a, as a time function:

algebraic and indicative recording form of values for the complex amplitude method

In such a case, its complex amplitude in indicative and algebraic form, respectively, will be:

algebraic and indicative recording form of values for the complex amplitude method

Take for example the voltage of the electrical circuit with frequency of 50 Hz:
