To determine

To calculate: The value of $F^{\prime }\left(5.5\right)$ and interpret the result when the flux of radio emission from the sun can be approximated by the model $F\left(t\right)=49.6\sin \left[0.602\left(t-1.48\right)\right]+111$ where t is number of years since January $1,1997$ and $F\left(t\right)$ is the average flux of solar emissions of a specified wavelength at time t.
