A function f can be visualized by drawing its graph in a (two-dimensional) coordinate system. The function graph of a function f can be defined mathematically as the set of all pairs of elements ( x | y ) for which y = f ( x ). The graph of a continuous function on a continuous interval forms a continuous curve.
The function plotter draws the function graphs of up to three real functions with one variable. The derivative of the functions 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.
f(x)=
g(x)=
h(x)=
In the function plot the parameter can be changed by moving the sliders. There are three constants a, b and c are available, which can be changed using the slider.
