Cosine Graphs: y = k + A cos(Bx + C)
This applet is designed to let you investigate the graphs of cosine functions.
The function being graphed in blue is: y = k + A cos (Bx + C).
This graph can easily be compared to the graph of y = cos(x) that is graphed in red.
Use the sliders to change the values of A, B, C, and k.
