Combining graphical, numerical, and symbolic viewpoints in calculus can be forbiddingly time-consuming and distracting without technological assistance. With technology, these viewpoints become practically accessible; hence, we use technology freely. So should our students.
Having said this, we emphasize that we do not intend to ``automate'' or ``computerize'' the calculus. We regard computers and graphing calculators strictly as instructional tools-albeit very powerful ones-to facilitate the crucial combination of graphical, numerical, and algebraic viewpoints. Our text exploits the capabilities of these tools to help students focus on the ideas that lie at the heart of the calculus.
