Cos(3pi/4+x)-cos(3pi/4-x) can be written as,
= cos 3pi/4 cos x - sin 3pi/4sinx - (cos 3pi/4cos x + sin 3pi/4sin x)
= cos 3pi/4 cos x - sin 3pi/4sin x - cos 3pi/4 cos x - sin 3pi/4 sin x
= -2sin 3pi/4 sin x
= -2 * (1/root 2) sin x
= -root 2 sin x
= cos 3pi/4 cos x - sin 3pi/4sinx - (cos 3pi/4cos x + sin 3pi/4sin x)
= cos 3pi/4 cos x - sin 3pi/4sin x - cos 3pi/4 cos x - sin 3pi/4 sin x
= -2sin 3pi/4 sin x
= -2 * (1/root 2) sin x
= -root 2 sin x
