Thread: Find equation of sine curve given maximum and mininum values.

Help!

Trig Graphs:Find an equation of a sine curve with the minimum of (-7pi/12,-11/4) and a maximum at (15pi/8,7/6)


i found the amplitude is 47/24 and the vertical shift is -19/24. Im confused about how to find the period and phase shift.

ok, so you have a possible form of

now, plug in the two points you were given one at a time to obtain two simultaneous equations. solve them to find and .

can you finish?
