" 12."(1)/(3+2sin x+cos x)

range of (12)/(1+3sin x+4cos x) is

The value of (2(sin2x+2cos^(2)x-1))/(cos x sin x cos3x+sin3x) is

int (1)/(2 sin^(2) x + 3 sin x cos x - 2 cos^(2) x ) dx =

Find the solutions x in [0,2pi] of: "sin" 2x – 12 ("sin" x - cos x) + 12 = 0

Find the solutions x in [0,2 pi] of : sin 2x-12 (sin x -cos x) + 12 =0 .

If y = Tan^(-1)[(5 cos - 12 sin x)/(12 cos x + 5 sin x)] , then (dy)/(dx) =

3. (sin x+cos x)(1-sin x cos x)=sin^(3)x+cos^(3)x

int(1)/(4sin^(2)x+3sin x cos x+2 cos^(2)x)dx=

Prove that: (i) sin 3x+"sin" 2x-"sin" x = 4 sin x cos((x)/(2))cos((3x)/(2)) (ii) ("sin" 3x+"sin" x)"sin" x+(cos 3x-cos x)cos x=0.
