____1____ +___1_____ = __2 sin A__
sin A + cos A sin A - cos A 1- 2 cos^2 A
L.H. S =_sin A - cos A_ +_sin A + cos A_
_sin A + cos A_ _ sin A - cos A_
=_ 2 sin A_ = _2sin A_
sin^ 2 - cos^2 1 - cos^2 - cos^2
= _2sin A_ ( Hence proved)
1-2cos^2 A R.H.S = L.H.S
. Using formula -> ( sin^2 = 1 - cos^2)
-> ( a^2 - b^2) = (a+b) (a-b)
I hope its help you....
