First equation of SHM is

#y_1=5[sin2pit+sqrt3cos2pit]#

#=>y_1=5*2[1/2sin2pit+sqrt3/2cos2pit]#

#=>y_1=5*2[cos(pi/3)sin2pit+sin(pi/3)cos2pit]#

#=>y_1=10sin(2pit+pi/3)->color(red)("its amplitude" A_1=10)#

Second equation of SHM is

#=>y_2=10sin(2pit+pi/4)->color(red)("its amplitude" A_2=5)#

Hence ratio of amplitude is

#A_1/A_2=10/5=2/1#
