 Hello and welcome to the session. In this session we are going to discuss the following question and the question says that from the graph determine the amplitude and period of the trigonometric function. Now let us start with the solution of the given question. Here we are given the graph of a trigonometric function. We have to find period and amplitude of the function from this graph. Now we know that period is the length of one cycle. Here we can see that length of one cycle is given by 2 pi minus 0 which is equal to 2 pi. So we say that period of the function is 2 pi. Now we shall find its amplitude. We know that amplitude is the distance between maximum height or minimum height and the midline. Here we see that the maximum height is at y is equal to 3 and the midline is given by y is equal to 0. So amplitude is given by maximum height that is 3 minus midline that is 0. So this is equal to 3. So this distance shows the amplitude. So for this graph we have period is equal to 2 pi and amplitude is equal to 3 which is the required answer. This completes our session. Hope you enjoyed this session.
