    look at the graph of \(y=\cot x\) |dw:1439968871914:dw|

    reflecting that over line \(y=x\) gives the graph of \(\cot^{-1}x\), yes ?

    Now, i am working on AREAS BETWEEN CURVES The problem is that whenever question ask find the area between the curves including arc(cotx) and something, so there would be 2 graphs of arc(cotx) So,there would be 2 different areas

    your professor must make it clear which graph you should be using

    my professor gave me the question already as homework and when i check my answer,my answer would not be there ?

    I see your point. The inverse graph when we take \(\cot x\) between \(0\) and \(\pi\) is |dw:1439969325071:dw|

    you get a different graph if you take some other interval

    yes, ask your professor which graph he wants the students to use

    Yes, depends on which part of the trig function you pick for the inverse. we need to agree on the domain/range first before doing the problems...
