Answer 1

10
$intlimits {sin3xsinx} , dx = intlimits {(1/2cos2x-1/2cos4x)} , dx =$$1/4*sin2x-1/8*sin4x$+C
11
$intlimits {cos5xcos3x} , dx = intlimits {(1/2cos2x+1/2cos8x)} , dx =$$1/4*sin2x+1/16*sin8x+C$
12
$intlimits {sin4xcos3x} , dx = intlimits {(1/2sinx+1/2sin7x)} , dx =$$-1/2*cosx-1/14*cos7x+C$
