This is the second disk of XYSEE.  The first disk is on #1507.  Both    
are needed to run the program.                                          
                                                                        
XYSEE allows teachers to create interactive computer tutorials for      
teaching high school and college level algebra, geometry and            
trigonometry.  At last, here's a method for the time-crunched teacher   
to be able to provide special, individualized help for the struggling   
student and enrichment for the advanced student!                        
                                                                        
XYSEE enhances students' understanding by incorporating graphics to     
help them visualize the curve represented by a given equation, and the  
effect upon the form of the curve when parameters within the equation   
change.  Tackles such subjects as points and lines, intermediate        
quadratics and trigonometrics, and advanced parametrics and             
composites.  In addition, interactive coverage is extended to forms     
such as triangles, user defined polygons (structured spline and         
free-form), and designs utilizing artistic mathematics.                 
                                                                        
The secret of this menu-driven instructional system lies in its use of  
macros which allow the instructor to formulate complex problems and     
demonstrate mathematical principles.  System features include moving    
window displays, function-sensitive statistics, and context-sensitive   
help screens.  With progressive overlays and multiple import facility,  
the package offers plot enhancement techniques, and sound and color     
control.  Both graphic and non-graphic printers are supported.  A       
demonstration tutorial and an extensive and well-written instruction    
manual are included.
