taking conjugate
(cosA-sinA)+1/(cosA+sinA)-1 * (cosA+sinA)+1/(cosA+sinA)+1
multiplying we get
=cos2A-sin2A+2cosA+1/2sinAcosA
=cos2A-sin2A+2cosA+sin2A+cos2A/2sinAcosA
on solving we get
=2cos2A+2cosA/2sinAcosA
=taking 2 common and divided
we get
=cosA+cos2A/sinAcosA
we can alsom write in the form o
cosA/sinAcosA +cos2A/sinAcosA
on solving we get
CosecA+cotA =R.H.S
