The material point participates in two oscillations passing along one straight line and expressed by the equations: x1 = A1 sin ω1t; x2 = A2 cos ω2t, where A1 = 1 cm; A2 = 2 cm; ω1 = ω2 = 1 s–1. Find the amplitude A of the complex movement, its frequency ν and the initial phase φ0; write the equation of motion.
