Technical information for professionals and students An extremely powerful computational tool, the TI-68 is designed to speed you through challenging calculations. It performs 254 functions, yet it's easy-to-use and a great value, too. he capabilities of the TI-68 go far beyond ordinary calculations. There's power to solve up to five simultaneous equations with real or complex coefficients. Forty complex-number functions - from simple arithmetic to advanced trigonometry. A convenient equa- tion replay feature for checking and editing your work. And versatile formula-programming capabilities. With the TI-68 you'll find it's easy to concentrate on problem-solving skills. To this end the TI-68 offers helpful prompts that guide you through simultaneous equations and formulas, gives you a straightforward way to enter complex numbers and has an easy-to-read, dot-matrix alphanumeric display. The result is a calculator that can solve complex problems but is sur- prisingly easy to learn and to use. With the TI-68 there's no time wasted learning to operate a compli- cated calculator. You can start solv- ing problems immediately and spend the rest of your time doing critical thinking and developing problem-solving strategies. Once that important work is done, you can rely on your calculator to pro- vide fast, accurate answers. If you're a student, this approach can help you speed through exams and homework. If you're a profes- sional, it can help you stay on schedule. And always with complete confidence in your answers.
