the most simple form of periodic motion is discussed in a trigonometry course; for example a traveling wave ( like a wave or sound wave) can be modeled with the equarion y=Acos(wt) where A is the amplitude and w is the frequency.
a) Suppose for a particular wave form, A=3cm and e=0.5 hertz. Use your calculator to sketch the graph of this wave for 0< (or equal) t < (or equal) 8 Pi . sketch the funcion below and plot the T intercepts.(exact value)
b) when is the particle at rest? Write the exact answer using pi as needed and using n where n is a nonnegative integer.All work must be shown. Plot/label these points on your graph in part a.
