    cotx=1/tanx tanx+1/tanx tanx/tanx =1

    Dude... tanx+1/tanx does not equal tanx/tanx

    Then yes, tanx+cotx is the answer.

    Are you deriving that from tanx+cotx? O_o

    ok, so first you change the equation in terms of Sinx and cosx so because tanx= sinx/cosx and cotx= cosx/sinx you're left with (sinx/cosx)+(cosx/sinx) now add them as you would any other fraction. ( Make sure to make them have common denominators before adding)

    oh. For 1/tanx+cotx, it would be 2cotx because cotx+cotx=2cotx
