(x sin x)/(cos^(2)x)

If f(x)=sqrt((x-sin x)/(x+cos^(2)x)), then lim(x rarr oo)f(x) is , then

lim_(x rarr oo)sqrt((x-sin x)/(x+cos^(2)x))=

Evaluate lim_(x to 0) sqrt((x-sin x)/(x+cos^(2) x)) .

lim_(x rarr0)(x-sin x)/(x+cos^(2)x)=

underset(x to oo)"Lt"sqrt [({x-sin x})/(x+cos^(2)(x))]=

Evaluate lim_(x to (pi)/(4)) (cos x - "sin" x)/(cos 2x)

Evaluate lim_(x to (pi)/(4)) (cos x - "sin" x)/(cos 2x)
