" If eas "x+sin x=sqrt(2)cos x" then "

cos x+sin x=sqrt(2)cos x then

sin x+cos x=sqrt(2)

If cos x+sin x=sqrt(2)cos x, prove that that cos x-sin x=sqrt(2)sin x

sin x+cos x=sqrt(2)sin5x

If sin x + cos x = sqrt(2) , then sin x cos x is equal to

If sin x + cos x =sqrt2 cos x , show that : sqrt2 sin x =cos x- sin x .

sin x + cos x = sqrt (2) cos A

If "sin" x + "sin"^(2) x = 1 show that: cos^(4)x + cos^(2)x = 1 (ii) If "sin" x + cos x =sqrt(2) cos x show that: sqrt2 sin x = cos x - sin x

sqrt(sin 2x) cos 2x
