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
