http://www.freemathvideos.com In this video tutorial I show you how to verify trigonometric identities. We verify trigonometric identities by following a couple of steps. First we choose a side to begin to simplify. It is a good idea to choose the side that is the most complicated" or that has the most operations such as division and adding and subtracting. We then look to simplify our side by applying operations
