Without graphing, find the exact coordinates of the first maximum point to the right of the y-axis for y=4 sin(2/3 x-pi/9)
----------------
Solve (2/3)x-(pi/9) = pi/2
-----
(2/3)x = (pi/2)+(pi/9)
-----
(2/3)x = (9pi + 2pi)/18 = (11/18)pi
--------
x = (3/2)(11/18)pi
--------
x = (11/12)pi
----------------
