x-t graph of SHM if the object starts from mean position

 

X = A sin ωt                                                  x= displacement

A= amplitude   

ω=angular frequency = 2πf

x-t graph of SHM if the object starts from extreme position

X = A cos ωt                                                   x= displacement

A= amplitude   

ω=angular frequency = 2πf
