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 ?

thats what you want to say na !

  • mayankdevnani
but i have one doubt ?
mayankdevnani
  • mayankdevnani
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

  • mayankdevnani
just rectify my doubt please ? @ganeshie8

  • ganeshie8
your professor must make it clear which graph you should be using
mayankdevnani
  • mayankdevnani
my professor gave me the question already as homework and when i check my answer,my answer would not be there ?

  • ganeshie8
I see your point. The inverse graph when we take \(\cot x\) between \(0\) and \(\pi\) is |dw:1439969325071:dw|
ganeshie8
  • ganeshie8
you get a different graph if you take some other interval

Question :- Find the area enclosed b/w y=arc(tanx),y=arc(cotx) and y-axis ?

so obvious, area would be different !

@ganeshie8

  • ganeshie8
yes, ask your professor which graph he wants the students to use
mayankdevnani
  • mayankdevnani
omg ! for one question,there would be 2 answers ?
mayankdevnani
  • mayankdevnani
Thanks ! @ganeshie8 now i am feeling confident on my answer !

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...
