 Graphic Calculus is a suite of programs to help students of different ages with the visualization, exploration and conceptualization of mathematical concepts. Graphing is a powerful graph plotter. Drawing graphs and curves in parameter representation. Axes can have labels such as cost, height etc. If your schoolbook uses word variables in graphs, your graph plotter ought to do the same. Graphic Calculus is using familiar mathematics notation. Sliding parameter and family parameter. Calculate tables. Zoom and trace. Finding the formula Students can test their knowledge of graphs. Draw the graph of an unknown function and guess the formula. Make your own collection of exercises. Line draws a line through two points and shows the changes of the formula as the point moves. Parabola Here you can draw the graph of a quadratic equation through two points. Exponential functions, the effects of changing parameters on the graph is shown. Trigonometric graphs show the construction of the sine, cosine and tangent from the unit circle. Advanced parts of the program Diagram of change shows the decrease and increase of functions in different ways. Gradient shows the drawing of a slope in a specific point as well as the graph of a gradient function. Area shows the area under a graph and calculates its value. Area also shows the area function of a given graph. Differential equation. The direction field and the solution through any starting point is plotted. Functions of two variables plots perspective drawings of surfaces z=f(x,y), either in 3D or as level lines. Cob-Web methods are to solve f(x)=x. Taylor polynomials to approximate functions with polynomials. Financial mathematics to visualize present value of an annuity or a bond. Linear Programming will solve lp-problems straightforward. Complex functions represents complex functions w=f(z), like sin(z), by drawing figures in the z-plane and their image in the w-plane. There are plenty of possibilities to adjust the program to the mathematical competency of your students. The program should especially benefit starting students.
