Reshaping College Mathematics Reshaping College Mathematics A project of the Committee on the Undergraduate Program in Mathematics Edited by Lynn Arthur Steen MAA Notes Series The MAA Notes Series, started in 1982, addresses a broad range of topics and themes of interest to all who are involved with undergraduate mathematics. The volumes in this series are readable, informative, and useful, and help the mathematical community keep up with developments of importance to mathematics.
