Question

How do you write the equation `sin45=y` in the form of an inverse function?

Answer 1

See below.

Explanation:

You don't have a function. A function would be of the form `f(x)=sinx` or `y =sinx`. The inverse of `f(x)=sinx` would be:

`f^-1(x)=sin^-1(x)`

In the example:

`sin(45)=1`

And:

`sin^-1(1)=45 , 135`
