A cosine function f can be visualized by drawing its graph in a (two-dimensional) coordinate system. The function graph of a cosine function f can be defined mathematically as the set of all pairs of elements ( x | y ) for which y = f (x). The graph of the continuous cosine function on a continuous interval forms a continuous curve.

f(x) = a⋅cos( b⋅x + c )

The function plotter draws the function graphs of the real cosine function. The derivative can be drawn with (d/dx) as dotted line in the graph. The integral can be started with select ∫. The integration range can adjusted with variation of the points at the function graph.
