" (b) "sin x sin(cos x)[NCERT](c)

Discuss the continuity of the following functions: (a) f(x) = sin x + cos x (b) f(x) = sin x - cos x (c) f(x) = sin x . cos x

In any triangle ABC,sin^(2)A-sin^(2)B+sin^(2)C is always equal to (A) 2sin A sin B cos C(B)2sin A cos B sin C(C)2sin A cos B cos C(D)2sin A sin B sin C

int ((sin x + cos x)(2-sin 2x))/(sin^(2)2x)dx= a) (sin x+cos x)/(sin 2x) +C b) (sin x- cos x)/(sin 2x)+C c) (sin x)/(sin x+cos x)+C d) (sin x)/(sin x-cos x)+C

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

8*sin(x/8)*cos(x/2)*cos(x/4)*cos(x/8)= .............. A) 8 sin x B) sin x C) cos x D) 8 cos x

(cos A)/(sin B sin C)+(cos B)/(sin C sin A)+(cos C)/(sin A sin B)=2

if A + B + C = pi then (cos A) / (sin B sin C) + (cos B) / (sin C sin A) + (cos C) / (sin A sin B) =

pi is the Fundamental period of (A) (1+sin x)/(cos x(1+cos ecx)) (B) |sin x|+|cos x| (C) sin2x+cos2x (D) cos(sin x)+cos(cos x)

If I=int (sin x + sin^(3)x)/(cos 2x) dx= A cos x + B log |f(x) |+c , then-
