ZOOM #7 ZTrig NOTE: If you do a ZOOM #7 ZTrig while in DEGREE mode, the x interval will be set from 352.5º to 352.5º, with the y interval from 4 to 4, and the increment set at 90º.

These vertical lines are not the asymptotes. They are simply the calculator behaving as it should in "Connected" mode  it is "connecting" the points.
This is a sinusoidal equation of the form y = Asin(B(x  C)) + D, where A is the amplitude, B is the frequency, C is the horizontal shift and D is the vertical shift. The period of this graph will be . When graphing such equations, it may be necessary to adjust the window to "see" the graph. If ZOOM #7 Trig is used with this graph, the screen will appear empty. The vertical shift tells you that the graph has been "raised" by 12 units. Adjust the yMax and yMin accordingly. The yMin has been set to 0 for this example to establish a reference point when viewing the graph. Enter the
