    (tanx+sinx)(1-cosx)=sin(Squared)xtanx

     L.H.S ..... [(sinx/cosx)+sinx](1-cosx)

                 [(sinx+sinx.cosx/cosx)](1-cosx)

                [ sinx(1-cosx)+sinxcosx(1-cosx)]/cosx

                 sinx-sinxcosx+sinxcosx-sinx cos^2 x/cosx

                 sinx-sinx cos^2 x/cosx

                  sinx(1-cos^2 x)/cosx
                  (1-cos^2x)sinx/cosx

                   sin(squared)x.tanx.......R.H.S
