A disk is rotating about its central axis like a merry-go-round. The angular position delta(t) of a reference line one the disk is given by delta(t)=-3.4 + 2.3t - .43t^2 with t in seconds, delta in radians and the initial angular position at zero. At what time does delta(t) reach its minimum value?
