${tan}^{- 1} b = a$ $tan^(-1)b=a$

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

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

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

or ${tan}^{- 1} b = a$ $tan^(-1)b=a$ .
