Задача 40323.

The particle takes part simultaneously in three harmonic oscillations occurring along the same direction according to the laws: x1=2cos(wt) cm, x2=4cos(wt p/4) cm, x3=2cos(wt p/2) cm. Determine the amplitude using a graphical method and the initial phase of the resulting oscillation.

A detailed solution with a brief note of the conditions, formulas and laws used in the solution, the derivation of the calculation formula and the answer.
If you have any questions about the solution, write. I try to help.
