Apr 12, 2024 · The basic sine and cosine functions have a period of 2π. The function sinx is odd, so its graph is symmetric about the origin. The function cosx 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.
Learn the cosine function as the ratio of the adjacent side to the hypotenuse of a right triangle. See the cosine graph, values, properties, identities, and examples of cosine in trigonometry.
Feb 1, 2024 · Learn how to graph the cosine function and its variations using a coordinate plane, key points, and transformations. Understand the properties and characteristics of cosine graphs, such as period, amplitude, phase shift, and symmetry.
In this section, we will interpret and create graphs of sine and cosine functions. Graphing Sine and Cosine Functions. Recall that the sine and cosine functions relate real number values to the x- and y-coordinates of a point on the unit circle. So what do they look like on a graph on a coordinate plane?
