2.cos(sin x)

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

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).

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

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

Integrate [(cos x+sin x)/(cos x-sin x)]

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

(cos x)/(1-sin x)=(1+cos x+sin x)/(1+cos x-sin x)

int(cos x+sin x)/(cos x-sin x)(1-sin2x)dx
