Visual Calculus 3.9

Here are some key features of "Visual Calculus":

Creating 2D function graphs, animations and table graphs:
· Functions can be in the form of explicit, parametric, piecewise, implicit and inequality
· Cartesian and polar coordinate systems
· Function graph animation
· Graph of inverse function
· Graph of derivative function
· Parity of function
· Maximum, minimum and inflexion
· Integral
· Root
· The length of curve
· Tangent and normal
· Curvature circle
· Point of intersection
· Area of intersectant field
· Use table data to create 2D line plot
· Scatter plot
· Curve smoothing
· Graph of ordinary differential equation
· Graph of limit
· Graph of series
· Step plot
· Stem plot
· High quality graph effect, the curve created is very smooth

· Creating 2.5D function graphs, animations and table graphs: Functions can be in the form of explicit and parametric
· Cartesian and polar coordinate systems
· Function graph animation
· Use table data to create 2.5D graph

Creating 3D function graphs, animations and table graphs:
· Functions can be in the form of explicit and parametric
· Cartesian, cylindrical and spherical coordinate systems
· D curve and 3D surface
· D curve and 3D surface animation
· Use table data to create 3D surface
· Surface by rotation
· Graph of partial derivative function
· Tangent line and normal plane of 3D curve
· Tangent plane and normal line of 3D surface
· D vector and it's subvector and projection
· D vector operation
· Material and light
· Texture
· Transparency
· Vertex, mesh and surface models
· High quality graph effect

Creating color map, contour plot and vector plot:
· You can create a single plot or add color map, contour plot, vector plot and surface
· to one graph
· Ability to set and modify the properties of function graphs, animations and table
· graphs

· Ability to move, zoom in, zoom out and rotate the graphs in plot area

· Ability to save graphs as pgp file or bmp file

· Ability to save animation as AVI file
