Advanced Grapher 方程式圖形繪圖軟體
Advanced Grapher是一個專門繪製方程式圖形的繪圖軟件,可以製作出多種方程式的圖形,非常適合國中,高中甚至大學相關科系的學生使用,對於學習數學一定能有事半功倍的效果
Features
works under Windows 95/98/Me/NT/2000/XP/2003/Vista/2008 operating system (or higher);
multiple-document interface;
plotting of up to 100 graphs on one coordinate plane (in one document);
supports graphing of the following graph types:
Y(x) and X(y);
graphs of tables;
R(a) - in polar coordinates;
X(t) and Y(t) - parametrical equations;
f(x,y)=0 - graphs of equations;
f(x,y)<0 and f(x,y)>0 - graphs of inequalities (and systems of inequalities);
dx/dy(x,y) and dy/dx(x,y) - slope fields.
you can specify color, style and width of lines, style and size of points, plotting by lines or points (or both), style of shading (for inequalities) for each graph. You can also change additional properties of graphs depending on graph type (e.g. amount of plotting points, plotting intervals, sorting (for tables), etc).
lots of design parameters of a coordinate plane (parameters of axes, grid, background, legend);
you can place custom text labels on the coordinate plane;
calculus features:
regression analysis (7 regression types and ability to automatically choose a regression type);
obtaining intersections;
analytical derivation;
determination of the equation of a tangent and its plotting;
numerical integration;
obtaining zeroes and extrema of functions;
built-in calculator
you can copy graphs as BMP or EMF to export them to the Word documents and save graphs as GIF, BMP or EMF;
