So, we have:

sin\left(\frac{\pi}{3} - \alpha\right)

It equals:

= sin\left(\frac{\pi}{3}\right)cos(\alpha) - cos\left(\frac{\pi}{3}\right)sin(\alpha)

We know that:

sin\left(\frac{\pi}{3}\right) = \frac{\sqrt{3}}{2}

And:

cos\left(\frac{\pi}{3}\right) = \frac{1}{2}

Therefore:

= \frac{\sqrt{3}}{2}cos(\alpha) - \frac{1}{2}sin(\alpha)

= \frac{\sqrt{3} \ cos(\alpha) - sin(\alpha)}{2}

If it can get any simpler than that... Then I'm lost...
