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.

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
