Solve the problem.
-A rotating beacon is located a distance $\mathrm { d }$ from a long wall. The distance $\mathrm { d }$ is given by $\mathrm { d } = 8$ tan $2 \pi \mathrm { t }$, where $t$ is the time measured in seconds since the beacon started rotating. Solve the equation for $t .$

To solve for $t$, we first isolate $t$ in the equation $\mathrm { d } = 8$ tan $2 \pi \mathrm { t }$. This gives $t = \frac { 1 } { 2 \pi } \arctan \frac { d } { 8 }$, by applying the inverse tangent function to both sides and dividing by $2\pi$.
