(35)
sinA/1+cosA=cosecA-cotA
from L.H.S
=sinA/1+CosA
=sinA/1+cosA×1-cosA/1-cosA
=sinA(1-cosA)/(1+cosA×1-cosA)
=sinA(1-cosA)/1-cos^2A)
=sinA(1-cosA)/sin^2A
=1-cosA/sinA
=1/sinA - cosA/sinA
=cosecA-cotA
(36)
=cosA/1-sinA = secA +tanA
from L.H.S
=cosA/1-sinA
=cosA/1-sinA×1+sinA/1+sinA
=cosA(1+sinA)/(1-sinA × 1+sinA)
=cosA(1+sinA)/(1-sin^2A)
=cosA(1+sinA)/cos^2A
=1+sinA/ cosA
=1/cosA+sinA/cosA
=secA+tanA
sinA/1+cosA=cosecA-cotA
from L.H.S
=sinA/1+CosA
=sinA/1+cosA×1-cosA/1-cosA
=sinA(1-cosA)/(1+cosA×1-cosA)
=sinA(1-cosA)/1-cos^2A)
=sinA(1-cosA)/sin^2A
=1-cosA/sinA
=1/sinA - cosA/sinA
=cosecA-cotA
