Show that the following statement is an identity by transforming the left side into the right side. (1 - cos e)(1 + cos e) = sin? e We begin by performing the multiplication on the left side. We can then use the Pythagorean Identity to simplify. (1 - cos 0)(1 + cos 0) = 1 - = sin? e Because we have succeeded in transforming the left side into the right side, we have shown that the statement (1 - cos e)(1 + cos e) = sin² e is an identity. + X - S
