Physics calculation about waves?
A wave traveling along a string is described by y(x,t)=0.00327sin(72.1x-2.72t)in which the numerical constants are in SI units (0.00327m,72.1radm^-1,and 2.72rads^-1)

A)What is the amplitude of this wave?
B)What are the wavelength,period and frequency of this wave?
C)What is the velocity of this wave?
D)What is the displacement y at x=22.5cm and t=18.9s.

Please help me.my book didn't have example for this type of question.Please show me yr working .Thank you.
