Задача 10633.

The point simultaneously performs two harmonic oscillations occurring in mutually perpendicular directions and expressed by the equations x \u003d sin (t / 2): y \u003d cos t (length - in centimeters, time - in seconds). Find the equation of the trajectory, build it to scale and indicate the direction of movement.

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.
