Solving a problem in physics, section 49, point 83 wave

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.
