self-answering problem

This recently won grand prize for best self-answering problem:

"At time t=0, water begins pouring into an empty tank so that the volume of water is changing at a rate \(\displaystyle V'(t)=sec^{2}t.\)
For time t=k, where \(\displaystyle 0<k<\frac{{\pi}}{2}\), determine the amount of water in the tank"

Just thought you'd find it interesting.

Note the emboldened tank. That's the answer....tan(k).
