Задача 40419.

The motion of a particle is a superposition of two harmonic oscillations along the x-axis of the following form: x1=2cos(2pt) cm and x2=2cos(2pt-p/2) cm. Using the vector diagram method, find the amplitude and initial phase of the resulting oscillation, write down the equation of the resulting fluctuations and plot it.

Detailed solution with a brief record of the conditions, formulas and laws used in the solution, derivation of the calculation formula and answer.
If you have any questions regarding the solution, please write. I try to help.
