`int ((sin 12x- sin 9x)/(2 cos 7x-1))dx=`

int(sin x)/(cos^(7)x)dx

int ((cos x + sin x) / (cos x-sin x)) dx

int(1)/(sin x sqrt(sin x cos x))dx=

int(1)/(sin x sqrt(sin x cos x))dx=

int (sin x) / ((1-cos x) (2-cos x)) dx

int(1)/(sin x sqrt(sin x cos x))dx

int (1)/(sin x sqrt(" sin x cos x")) dx =

int (cos 9x +cos 6x )/( 2 cos 5x-1)dx =A sin 4x +B sin+C, then A+B is equal to: (Where C is constant of integration)

int (cos 9x +cos 6x )/( 2 cos 5x-1)dx =A sin 4x +B sin+C, then A+B is equal to: (Where C is constant of integration)

Evaluate: int(1)/((sin x-2cos x)(2sin x+cos x))dx
