Question 856400
Graph the function y=2sin(x-2pi/3). To draw the graph, plot all x-intercepts, minima and maxima within on period. 
-------
One period = 2pi
----------------------
{{{graph(400,400,-pi,pi,-2.5,2.5,2sin(x-2pi/3))}}}
------------
(-2.618,2) ; (-1.57,1) ; (-1.047.0) ; (0.5236,-2) ; (2.0943,0)
