The main features of College Mathematics Drawing Expert 2.6 are as follows: 1. The form of two-dimensional graphic function can be explicit, parametric, implicit or inequality; Cartesian coordinate system and polar coordinate system; Functional graphic animation; The graph of inverse function; Derivative function diagram; Parity of function; Maximum, minimum and inflection point; Integral; Root; Arc length; Tangents and normals; Circle of curvature; Intersection point of two-dimensional curve; The area of the intersection area; Two-dimensional linear graph based on tabular data; Scatter chart; Smooth curve; Ladder diagram; Matchstick map; Using anti-aliasing technology, the curve smoothness is high. 2. The function form of two-dimensional semi-graphic can be explicit and parameterized; Cartesian coordinate system and polar coordinate system; Functional graphic animation; Strip chart based on tabular data. 3. The function form of 3D graphics can be explicit or parameterized; Cartesian coordinate system, cylindrical coordinate system and spherical coordinate system; Three-dimensional curves and surfaces; 3D curve and surface animation; Three-dimensional surface based on tabular data; Rotating surface based on two-dimensional curve; Materials and lighting; Vertex, wireframe and surface model; High-quality graphic effects. 4. Creating chromatogram, contour map and vector map can create a single graph. You can also superimpose different graphics on a picture. 5. Set and modify the properties of graphics and animation. 6. Translate, reduce, enlarge and rotate the generated figure 7. Save the generated graphics as pgp and bmp files 8. Save the animation as AVI file 9. Free tools, math calculators, etc. File size: 3.44M Developer: Hantu Software Version: 2.6 Operating System: Win 2003/ Win XP/ Win NT/2K/ Language Interface: Chinese-2.pchome.net/0q/uh/HT20.
