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.
