Question:
Describe the transformation which maps the function y = tan x onto the function y = tan x

Answer:
(See attachment) The transformation is reciprocal.

Inverse tan is not the same as 1/tan

Can you help explain how to answer this question then please?

I don't know what your question means. What are you trying to do?

I do not know what you mean by that.
Perhaps you wish to state,
Find a one-to-one function which maps tan x ONTO x?
Then the answer is the inverse tangent.
But the inverse tangent has nothing to do with the reciprocal.
