# Product Of Sine And Cosine

**Geometry**Level 2

Determine the values of \(k\) so that the inequality \(\displaystyle{\sin x \cos x\geq k}\) is satisfied \(\forall x \in \mathbb{R}\).

If \(k^2\) can be written as \(\displaystyle \frac{a}{b}\), where \(a\) and \(b\) are relatively prime integers, find \(a+b\).
