A revolutionary text that requires no special advanced training on the instructor's part, and which needs no supplementary manuals to use. The text's "calculus-as-a-foreign-language" approach, using immersion, reading, and writing, promotes mathematical literacy and comprehension. Highly accessible and diverse "conversations" allow the text to be customized for business, science, pre-health, humanities, social science, or mathematics majors, and for classes at any level.
