y=2sin(3t-(pie)/4)+8between (pie) and 4(pie)
y=2sin(3t-(pie)/4)+8 for which y attains the minimum value.
Minimum value of function is -1. So minimum value of y could be 6.The real question is does there exist a t between (pie) and (4pie), such that this happens.
sin(3t-(pie)/4) = -1 means that
So between an , we have three angles that satisfy:
and the minimum value is
