This is an online textbook for a one semester calculus course aimed at business students.
The material covered is fairly standard: differentiation and integration without trigonometry, partial derivatives and optimization of functions of several variables.
There are several characteristics that differentiate the text from other texts:
Excel is used as the main computational engine throughout the text and the needed Excel skills are taught rather than assumed.
Examples, exercises, and vocabulary are tailored to uses in a business curriculum.
There is a modeling thread throughout the text.
Webwork versions of exercises are available on request.

Asking and answering questions about what culture entails and examines the fundamental properties and intertwining nature of language and culture. This text explores linguistic relativity, lexical differences among languages and intercultural communication, including high and low contexts.

Changes to the original works were made by Manon Allard-Kropp in the Department of Language and Cultural Studies to tailor the text to fit the needs of the Languages and World View course at the University of Missouri–St. Louis. Materials from the original sources have been combined, reorganized, and added to by the current author, and any conceptual or typographical errors are the responsibility of the current author. This work was developed with support from the University of Missouri–St. Louis Thomas Jefferson Library, with special thanks to librarians Judy Schmitt and Helena Marvin.
