It is available from free online right here at this link. In fact Stephen Wolfram has an excellent guide to starting to use the language.
Good luck on your homework! Try to watch some Mathematica/Wolfram Language instructional videos. Read about WL syntax, square brackets are only for calls to/defining functions, not for ordering expressions, use regular parens for that (). Google and other resources are your friend. When a message is issued, read it carefully and try to figure out what it means. The fact that FromAbove was blue means that it doesn't have a value. We will look at a variety of these, starting. The coloring of things in a notebook can give you hints about what is going on. In addition to being a powerful programming tool, Mathematica allows a wide array of plotting and graphing options. (* this just works with the modifications to h *) Then with the above modifications, the Plot call evaluates properly. (* the values of the Direction option are + or - 1, you can play around with the below *) Consider the following data to be plotted (stored as sdata ): In 1.
If you read the error message and look at the documentation for the Limit function you will see that FromAbove is not a supported value, nor is it something that Mathematica even knows about. The Wolfram Language offers extensive support for plotting all kinds of data in many different ways. Now you can look at why Direction wasn't working properly for you. Wolfram Knowledgebase Curated computable knowledge powering Wolfram|Alpha.Not to do your homework for you, I have made an edit to your first problem to make it work (changed the numbers so you have to implement it yourself, but it should give an idea). Wolfram Universal Deployment System Instant deployment across cloud, desktop, mobile, and more. Tutorial for Mathematica & Wolfram Language. Wolfram Data Framework Semantic framework for real-world data. How to make graphs of polynomial functions, regions of inequalities.
