prove:(SinA + CosA)^2 + (SinA - CosA)^2 = 2 L.H.S Sin2A + 2 SinA . CosA + Cos2A + Sin2A - 2 SinA . CosA + Cos2A
( + & - 2 SinA . CosA will get cancelled) ( Sin2A + Cos2A = 1)
1 + 1 2 = 2 L.H.S = R.H.S
( + & - 2 SinA . CosA will get cancelled) ( Sin2A + Cos2A = 1)
1 + 1 2 = 2 L.H.S = R.H.S

after the L.H.S on first line starts the solution
