As either sine squared or cosine squared gets closer to one the amount left for the other diminishes. It can be seen from the geometry. The hypotenuse is one and is longer than either of the other sides. As one side gets closer to one, the other must get closer to 0. movies that couldn\u0027t be made todayWebThe graphs of \(y = \sin{\theta}\) and \(y = \cos{\theta}\) can be plotted.
