Geometer's Sketchpad V4 50 User

• Accomplish Euclidean constructions with the drawing tools in the Toolbox and with commands in the Construct menu.
• Go beyond Eucldean constructions using commands in the Transform menu to construct translations, reflections, rotations, dilations, and iterations by fixed, computed and dynamic quantities.
• Enter the realm of algebra using the Graph menu to plot functions and work in rectangular or polar coordinate systems.
• Calculate and plot derivatives of functions: see derivatives both graphically and symbolically.
• Create animations that trace out sine waves, and explore other trigonometric identities.
• Encapsulate complex constructions in single steps with user-designed custom tools, extending Sketchpads capabilities.
