83. The displacement of the luminous point on the oscilloscope screen is the result of adding two perpendicular oscillations, which are described by the equations: 1) x = Asin3ωt and = Asin2ωt; 2) x = y = and Asin3ωt Acos2ωt; 3) = x and y = Asin3ωt Acosωt. By applying a graphical method of addition and following the scale, to build a path of a luminous point on the screen. Take A = 4 cm.
