Find equation for sine curve given maximum & mininum values

Help!

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.


thanks

The minimum and maximum are half a cycle apart. The phase shift is determined by the midpoint (in x) from the min to the max.
