The equation for displacement is given as
 
x = Asin∂   
 
Given –    x =2 cm,  A= 4cm,   frequency = 12 Hz
 
We know, W = 2× pi× f
Putting values in above equation we get  W = 24 × pi --------------------------------------- (1)
 
Using,  x = Asin∂ 
          2  = 4sin∂
         ∂ =  30 degree----------------------------------------------------------------------------------( 2 )
 
Putiing values of 1 and 2 in eqation ----  x = Asin ( Wt + Angle )
 
x = 4sin ( 24 pi t  +  30 )...........Ans.
