See the explanation below

Explanation:

Here are a few tricks :

#"displacement "x=asin(omegat+phi)#

where #a="amplitude"#

#"velocity"=dx/dt=aomegacos(omegat+phi)#

#v_(max)=aomega#

#"acceleration" =(d^2x)/dt^2=-omega^2asin(omegat+phi)=-omega^2x#

#"maximum acceleraton"=omega^2a#

#omega=(2*pi)/T# where #T="period"#

#"The angular frequency"=f=omega/(2pi) #
