This site provides access to the latest versions of all Texas Instruments Graphing Calculator Programs and Microsoft Excel Worksheets for all Houghton Mifflin mathematics textbooks by Geoffrey C. Berresford and Andrew M. Rockett that are currently in print. Each calculator program is compressed in an archive together with complete instructions in PDF format. To make full use of these materials, you need StuffIt Expander, Acrobat Reader, and the TI-Connect or TI-Graph Link software (and connecting cable!) for your calculator. These software programs are available for free by "clicking" on the preceding links, and the Graph Link cable is available wherever TI Graphing Calculators are sold.
