6-58.

Ryan thinks that sin *x* = 0.3 is the same as sin^{−1}(0.3) = *x*. Is Ryan correct? What does Ryan have to take into consideration for these two expressions? Homework Help ✎

Sin *x* = 0.3 has infinite solutions unless we are working with a restricted value of *x*.

The expression of sin^{− 1} 0.3 = *x* has only one solution when sin^{− 1} *x* is a function.
