![]() To plot the graph of f(x, y) = 0, use f1(x) = zeros(f(x, y), y). Here is a trick to “fake” implicit 2D plotting in Nspire CAS. When will the distance between them be the smallest? The next slide shows the situation.ĭifferent Objects in the Same 2D Plot Windowĭifferent Objects in the Same 2D Plot Window A word on implicit plotting: it is a must for multiple variable calculus (but probably not so important for college level). ![]() Two objects are moving in the plane, with respective given position at time t. Slider bars, animations, dynamic geometry, styles and colors make each of these 2D plot windows very attractive and useful for teaching mathematics and sciences.ĭifferent Objects in the Same 2D Plot Window Slider bars/animations, dynamic geometryand calculus are now used by teachers for showing many concepts: this was never done before. 3D parametric surfaces and curves (OS 3.2) Today, wewillmainly focus on parametric 3D plotting.ĭifferent Objects in the Same 2D Plot Window (In OS 3.2) The 2D plot window graph Entry/Edit accepts up to 7 different types but 2D implicit plots are still missing.multiple 2D plots window(functions, parametric, scatter plot, etc.).interactive geometry: « experimentalmathematics ».animations : powerfultool for teaching.(better for solving, Taylor polynomials, specialfunctions, …).What’s New with TI-Nspire CAS?
