" 2.2."x^(4)(5sin x-3cos x)

int(2 sin x+3 cos x+4)/(3 sin x+4 cos x+5)dx.

If int(3cos x-2sin x)/(4sin x+5cos x)dx=Ax+B log|5cos x+4sin x| then (A,B)=

" If "sin^(2)x+sin x cos x-6cos^(2)x=0" and "-(pi)/(2)ltxlt0," then value of "cos2x" is " -3/5 3/5 -4/5 4/5

Evaluate: int(4sin x+5cos x)/(5sin x+4cos 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.

if 3sin x+4cos x=5, then 4sin x-3cos x

Find the period of (5 sin x + 3 cos x)/(4 sin 2x + 5 cos x)

If 3 sin x+ 4 cos x =5 then 4 sin x -3 cos x is equal to
