list the period, amplitude, interval, and phase shift of: g(t)=5/2sint-pi
i know the amplitude is 5/2 but everything else im not getting.
the regular formula for these is
A is the amplitude
B is the period which you use (2pi/b) to solve.
C is just a constant i assume.
D is the vertical shift.
If theres a neg. A then its a face shift; and the formula changes. but i don't think this is a case for that.
Please help. Thank you.
