Functions in 2D and 3D
Functions of the form F(x) can be integrated, differentiated or searched for zeroes and extrema. Cartesian as well as Polar coordinates can be chosen and functions can be represented in parametrized form (i.e. y(t) versus x(t)).
F(x,y) can be represented by Shaded surfaces, Contourplots and Cross-sections through Contourplots. The 3D viewer provides a quick view of the shaded surface from different viewing angles and distances. Rotate the surface, zoom in/out or change the position of the light source by moving the mouse.
