Question

How do you write the equation `tana=b` in the form of an inverse function?

Answer 1

`tan^(-1)b=a`

Explanation:

When we write an inverse function, we are identifying the angle, whose trigonometric ratio is known.

In this case as `tana=b`, we have the angle `a`, whose tangent ratio is b.

And inverse function is written as `tan^(-1)b`, which is equal to
`a`

or `tan^(-1)b=a` .
