Inverse Trig Functions - Cornell University

The other inverse functions are similarly defined using the corresponding trig functions. Some Useful Identities Here are a few identities that you may find helpful. cos−1(x)+cos−1(−x) = π sin−1(x)+cos−1(x) = π 2 tan−1(−x) = −tan−1(x) Practicing with the Inverse Functions Example 1: Find the value of tan(sin−1(1 5). ................
