Let f be an odd function defined on the set of real numbers such that for x ³ 0, f(x) = 3 sin x + 4 cos x. Then f(x) at x = 11 6 p – is equal to:

Let $f$ be an odd function defined on the set of real numbers such that for $x \geq 0, f(x)=3 \sin x+4 \cos x$.

Then $\mathrm{f}(\mathrm{x})$ at $\mathrm{x}=-\frac{11 \pi}{6}$ is equal to:
