Sine and Cosine Graphs Worksheets
What are the Trends of Graphs of the Sine and Cosine Function? Sine and cosine functions display the values to the x and y coordinates of a point on the unit circle. These can also be plotted on a coordinate system. Both these graphs follow strict trends, and these are; The basic sine and cosine functions have a period of 2π. Which means after 2π, the graph repeats itself. The function of sin x is odd, so its graph is symmetric about the origin. The function cos x is even, so its graph is symmetric about the y-axis. The graph of a sinusoidal function has the same general shape as a sine or cosine function.
The mathematician does not study pure mathematics because it is useful; he studies it because he delights in it and he delights in it because it is beautiful.
