If `sqrt(sin x)+ cos x = 0` then sin x =

If sin x+cos x=0 then |sin x-cos x|=

If "cos x + sqrt("sin" x) = 0, then x =

If f(x)=|(10(sqrt(cos x)-sqrt(sin x))(sqrt(cos x)+ sqrt(sin x)))/(cos x+ sin x)| then number of natural numbers in the range of f(x) is

If sin x + sin y = sqrt (3) (cos y-cos x), then sin3x + sin3y =

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

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

Solve sin x + cos x - 2sqrt(2) sin x cos x = 0
