Observe the solution of the exercises and analyze the process and reasoning used. To VERIFY AN IDENTITY: Work on each side separately and make sure you don’t move things from one side to the other! You can work on both sides at the same time – but you just can’t move things from one side to the other. We will again run into the Pythagorean identity, sin2 x + cos2 x = 1 for all angles x. We will re-write everything in terms of sin and cos and simplify. . However, verifying these identities can often be a challenging task, especially for those new to trigonometry. jwbf2hq cfepqus6 hw0c 3ramzqo7 li4pz 3xpz h8 396qv qirwt ve9fz
