Hi floridaboylol, and welcome to the forum. What difficulty are you having? If you look in any appropriate textbook or find similar questions on this site by searching for sinusoid(al), you can find detailed instructions to follow for questions of this type. You can deduce the wave's amplitude, wavelength, etc., from the information given in the question, allowing you to write an appropriate equation. Finishing the question is then easy.
