Heya...
====== Solution =======
1-cosQ+sinQ/1+sinQ
= 1-cosQ+sinQ/1+sinQ X 1+cosQ+sinQ/1+cosQ+sinQ
= (1+sinQ^2)-(1+cosQ+sinQ)
----------------------------------------
(1+sinQ)+(1+cosQ+sinQ)
= (1+sinQ)(1+sinQ)-[(1+sinQ)(1-sinQ)]
---------------------------------------------------
(1+sinQ)+(1+cosQ+sinQ)
= (1+sinQ)[(1+sinQ)-(1-sinQ)]
---------------------------------------
(1+sinQ)(1+cosQ+sinQ)
2sinQ/1+cosQ+sinQ = Y
Thank you
