    Average rate of change of h(t) beween to points a and b can be found as follows


     \frac{h(b)-h(a)}{b-a}

     \frac{h(\frac{4\pi}{3})-h(\frac{3\pi}{4})}{\frac{4\pi}{3}-\frac{3\pi}{4}}

     \frac{\sin(\frac{4\pi}{3})-\sin(\frac{3\pi}{4})}{\frac{4\pi}{3}-\frac{3\pi}{4}}

    Can you take it from here?
