Question 1146951: 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. For what values of t does the weight reach its farthest point below its central position?

These time moments "t" are the roots of the equation


    3.8t - 2.1 = 3pi%2F2+%2B+2k%2Api,  k = 0, +-1, +-2, +-3, . . .
