Consider the trigonometric function y= 2sin - Wewill il out the table and plot S points so that we can see the graph and sketch it. Solve for from last line Solve for y The S points arex from row 2 y value from row 4 her we have 5 points, we know that the graph of sine looks like a wave. Hence the graph can be sketched with the 5 points. You can extend the graph by copying the graph from the 5 points to the left and right because the graph of sine function is periodic
