Solving a problem in physics, section 3, paragraph 97 w

97. Add two swings same direction expressed by the equations: x1 = A1cos2π / T (t + τ1); x2 = A2cos2π / T (t + τ2), wherein A1 = 3 cm; A2 = 2 cm; τ1 = 1/6 sec; τ2 = 1/3 s; T = 2 s. Construct a vector diagram of the addition of these oscillations, and write the equation of the resulting fluctuations.
