Graphs of Cosine and Sine. Cosine and sine of an angle θ are defined to be the x and y-coordinates of the point P on the unit circle with the property that the line from O to P makes and angle θ with ...

A graph of a functions is a visual representation of the pairs (input, output), in the plane. This applet will help you to understand the connection between the graph of a function and a function as ...

Mathematics on this graph isn’t limited to algebraic expressions. You can also plot graphs for trigonometric equations (equations that use sine, cosine, and tan, etc.), establish graphs for ...

With static graphs and equations, it's possible to get a handle on the rules of what various functions do and mean. ... Next, think about the relationship between sine, cosine and the circle.
