text: # Two simple harmonic motions are represented  by equation  y1=10sin (4×22÷7t+22÷7÷4)and y2=5 (sin 322÷7t+root3cos322÷7t).their amplitudes are in what ratio

  Dear student
  
  y1 = 10 sin (4*pi*t + pi/4)
  y2 = 5 sin 3*pi*t + sqrt(3) cos 3*pi*t
  y2 = $\sqrt$34 sin (3*pi*t + @)
  Hence ratio of amplitude of y1 and y2
  = 10/$\sqrt$34

  Dear student,
  
  y1 = 10 sin (4πt + π/4)
  y2 = 5 sin 3πt + 3 cos 3πt
  y2 = 34 sin (3πt + @)
  Hence ratio of amplitude of y1 and y2
  = 10/34
  
  Thanks and regards,
