If `sin (sin x + cos x) = cos(cos x -sin x),` then the largest possible value of `sin x,` is

If sin(sin x+cos x)=cos(cos x-sin x), and largest possible value of sin xis(pi)/(k), then the value of k is

sin x sin (cos x)

sin x sin (cos x)

(sin x + cos x)^2 + (sin x - cos x)^2

int ((cos x + sin x) / (cos x-sin x)) dx

int(sin x cos x)/(1+sin x+cos x)

(sin x+x cos x)/(x sin x-cos x)

(sin x + sin 3x)/(cos x - cos 3x) = ?

int (cos x-sin x) / ((cos x + sin x) dx)

int(sin x+cos x)/(sin x-cos x)dx
