276 • Chapter 7: Solving Calculus Problemsu(x,y)71–2x2–2y27.4 ConclusionThis chapter has demonstrated how Maple can be used to aid in the investigationand solution of problems using calculus. You have seen how Maplecan visually represent concepts, such as the derivative and the Riemannintegral; help analyze the error term in a Taylor approximation; and manipulateand solve ordinary and partial differential equations, numericallyas well as symbolically.
8 Input and OutputMaple provides convenient ways to import and export raw numerical dataand graphics. It presents individual algebraic and numeric results in formatssuitable for use in FORTRAN, C, or the mathematical typesettingsystem L A TEX. You can export the entire worksheet as a file in any of thefollowing formats: HTML or HTML with MathML, L A TEX, Maple Input,Maple Text, Maplet application, Plain Text, or Rich Text Format. Youcan cut and paste results, and export either single expressions or entireworksheets.This chapter discusses the most common aspects of exporting andimporting information to and from files. It introduces how Maple interactswith the file system on your computer, and how Maple can begininteracting with other software.In This Chapter• Reading Files• Writing Data to a File• Exporting Worksheets• Printing Graphics8.1 Reading FilesThe two most common cases for reading files are to obtain data and toretrieve Maple commands stored in a text file.• The first case is often concerned with data generated from an experiment.You can store numbers separated by whitespace and linebreaks in a text file, then read them into Maple for study.
