Question 1146941: A weight is suspended from a spring and vibrating vertically according to the equation f(t) =25.2sin(3.8t-2.1), where f(t) centimeters is the directed distance of the weight from its central position at t seconds, and the positive distance means above its central position. Find the times when the weight is at its central position.

.
These times "t" are the roots of the equation


    3.8t - 2.1 = ,  k = 0, +-1, +-2, +-3,  . . .
