    \[\huge f'(x)\frac{ sintcost }{ 25 \pi }\]

    Are they asking to solve for t, equation the derivative to zero?

    At t=0, the derivative will be 0. For 0<t<\(\frac{\Large\pi}{2}\) the derivative will be positive because sin and cos will both be positive.

    \[T = 0 + \left| \delta t \right|\]
