Dear aabhas ,


the genreal equation of shm is     x(t) =  Asin(wt)


so just plug in the values given in the quesiton and solve ....x


x = A sinw ------(1)


y = Asin2w - Asinw


y =2Acosw *sinw - Asinw


y = (2cosW -1) *x


cosw =(y/x+1)/2 =  (x+y)/2x


so sinw  = (1-cos2w)1/2  = ( 1 -(x+y/2x)2)1/2  =  (3x2-y2-2xy)1/2 / 2x


putting in eqn 1


A = x/sinw  = 2x2/(3x2-y2-2xy)1/2
