Question

the inverse of unit third degree is called as​

Answer 1

Answer:

The trigonometric functions aren't really invertible, because they have multiple inputs that have the same output. For example, \sin(0)=\sin(\pi)=0sin(0)=sin(π)=0sine, left parenthesis, 0, right parenthesis, equals, sine, left parenthesis, pi, right parenthesis, equals, 0. So what should be \sin^{-1}(0)sin

−1

(0)sine, start superscript, minus, 1, end superscript, left parenthesis, 0, right parenthesis?

In order to define the inverse functions, we have to restrict the domain of the original functions to an interval where they are invertible. These domains determine the range of the inverse functions.

The value from the appropriate range that an inverse function returns is called the principal value of the function.
