# Inverse trigonometry watch

1. Hi. I have a problem and am not convinced I can do it. I have to solve:

y=arctan ( k tan (x) ) where k is a constant

I would have thought that the constant means you cannot do it? Am I missing something obvious or can it not be done? (at least to further maths a2 standard.)
(This is part of DE coursework not a stand-alone question)
2. What do you mean by 'solve' in this case? It might be better to post the whole question.

I have the equation of a line

y = (k/b) * (tan(kb×( (26−x)/m) ) )

I have several data points the line needs to fit and was looking to find values for k and b the constants.
