sin2x can be rewritten
ya as 2sinxcosx but what next?
2sinx + 2cos x + 4sinx cosx = 1 2sinx( 1 + 2cosx) + 2cosx = 1 2sinx(1+ 2cosx) + (1+2 cosx) =2 (1+ 2sinx)(1+2cosx) = 2

I don't have much idea next, leme see
yes thanks a lot thats absolutely fine! i got an idea to solve the question
Will you share that idea ?
2sinx=1; 2cosx=1 and further by the formulae sin theta =sin alpha and so on....
sinx and cosx both can not be 1/2 for the same value of x, you're logic is flawed.
Its quite complicated to solve this, are you sure you have the right ques ?
i know there may be some problem in the question or the expansion....wait..question is cosx+sinx-sin2x=1/2 so in that way it can be solved
-sin2x !!
its easily solvable then
2cosx + 2sinx - 4sinx cosx = 1 2sinx(1 - 2cosx) = (1-2cosx) =>(2sinx)(1- 2cosx) =0 BAZINGA !
wow!!! thanks....i was a bit confused....thanks a lot!
Glad to have helped.
Correction :
it'll be (1-2sinx)(1- 2cosx) =0
ya i got that....k thanks bye gtg
