The graph of the relationship between the deviation from the equilibrium position and the angle 
for two pendulums is given below.
Describe the oscillations of the two pendulums.
At what angle will the instantaneous displacement from the equilibrium position be the same for both pendulums?
What will be the deviation from the equilibrium position if the amplitude of oscillation for both pendulums is 4 cm?
.
, so it oscillates according to the function:
radians.
