The period of the sine curve is the length of one cycle of the curve. The natural period of the sine curve is 2Ï. So, a coefficient of b=1 is equivalent to a period of 2Ï. To get the period of the sine curve for any coefficient b, just divide 2Ï by the coefficient b to get the new period of the curve.
The problem may be more clearly thought of as y = 2(-sin x). This graph is a reflection in the x-axis of the graph y = 2 sin x. The amplitude of 2 tells us that the graph will have a vertical stretch. How to use your TI-83+/84+ graphing calculator for graphing sinusoidal functions. Click calculator. sine wave, or sinusoid, is the graph of the sine function in trigonometry. A sinusoid is the name given to any curve that can be written in the form (A and B are positive).
