The function f(x)=(a sin x+b cos x)/(c sin x+d cos x) is decreasing,if

If the function f(x) = (K sin x + 2 cos x)/(sin x + cos x) is strictly increasing for all values of x, then

The function f(x)=(a sin x+b cos x)/(c sin x+d cos x) is decreasing,if (i) ad-bc>0 (ii) ad-bc 0 (ii) ab-dc<0

Integral of form (a sin x+b cos x)/(c cos x+d sin x)

If x is real and (a sin x +b cos x)/(c sin x +d cos x) has neither maximum nor minimum then

Differentiate (sin x-x cos x)/(x sin x+cos x) with respect to x.

If f(x)=(cos x-sin x)/(cos x+sin x) then f^(-1)(x)=
