WebbHere is an example of using a sum identity: Find sin15∘. If we can find (think of) two angles A and B whose sum or whose difference is 15, and whose sine and cosine we know. … WebbTo sum up, only two of the trigonometric functions, cosine and secant, are even. The other four functions are odd, verifying the even-odd identities. The next set of fundamental identities is the set of reciprocal identities, which, as their name implies, relate trigonometric functions that are reciprocals of each other. See Table 3.
