secx+cscx-cosx-sinx=sinxtanx+cosxcotx
This is as far as I got
(1/cosx)+(1/sinx)-cosx-sinx=sinx(sinx/cosx)+cosx(cosx/sinx) I turned them into sin and cos
(sinx/sinxcosx)+(cosx/sinxcosx)-cosx-sinx = (sin2x/cosx)+(cos2x/sinx) I multiplied the second equation and I tried to get similar denominators in the first equation
I'm lost at what to do next.
