text solution here;
I was solving this today...got stuck and wanted to consult here...but i eventually found the solution...any insight/alternative approach is welcome...
My approach;
...
##\sin^2y+ cos^2 y= 2a^2-2a \sin x - 2a\cos x+1##
It follows that,##2a(\sin x + \cos x)=2a^2##
##\sin x+\cos x=a##
cheers.
