Find the period of cos(cos x) + cos(sin x).

Find the period of cos (cos x) + cos ( sin x) .

Find the period of cos(cos x)+cos(sin x)

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

The number of solutions that the equation sin (cos (sin x))= cos (sin (cos x)) has in [0, (pi)/(2)], is "_____"

Ltquad x rarr0 (1-cos ^ (2) (sin x) -cos (sin ^ (2) x) + cos ^ (2) (sin x) cos (sin ^ (2) x)) / (x ^ ( 6)) =

Period of f(x)=cos(|sin x|-|cos x|) is

2tan2x = (cos x + sin x) / (cos x-sin x) - (cos x-sin x) / (cos x + sin x)

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

Integrate {(cos x-sin x)/(cos x+sin x)}
