put this solution on YOUR website!sinx + cosx - sinxcosx = sin^2 x + cos^2 x
cosx + sinx - sinxcosx = 1
cosx + sinx = 1 + sinxcosx
cos^2 x + 2cosxsinx + sin^2 x = 1 + 2sinxcosx + sin^2 x cos^2 x
cos^2 x + sin^2 x = 1 + sin^2 x cos^2 x
1 = 1 + sin^2 x cos^2 x
0 = sin^2 x cos^2 x
sin^2 x = 0
Ans: 2(pi)k
cos^2 x = 0
Ans: (pi)/2 + 2(pi)k
~k is any integer
