Tutorial Exercise Sketch the graph of the function showing the amplitude and period of the function below y cos 3t Step 1 The question asks us to sketch the function y cos 3t First note that the function is a cosine function and will ha that basic shape E From the text the general form of a non shifted cosine function is y a cos bt The text also tells us that a is the amplitude that is the maximum height above zero that the function attains Note that the amplitude must be a un number Looking at our function the amplitude is
