About our authors Eric Schulz has been teaching mathematics at Walla Walla Community College since 1989 and began his work with Mathematica in 1992. He has an undergraduate degree in mathematics from Seattle Pacific University, and a graduate degree in mathematics from the University of Washington. Eric loves working with students and is passionate about their success. His interest in innovative and effective uses of technology in teaching mathematics has remained strong throughout his career. He is the developer of the Basic Math Assistant, Classroom Assistant, and Writing Assistant palettes that ship in Mathematica worldwide. He is an author on multiple textbooks: Calculus titles with Briggs, Cochran, and Gillett, and a Precalculus title with Sachs and Briggs (where he writes, codes and creates dynamic eTexts combining narrative, videos and interactive figures using Mathematica and CDF technology).Julianne Connell Sachs has undergraduate degrees in Mathematics and Spanish, and a graduate degree in Mathematics from Western Washington University. She taught math and physics in Guatemala for 1 year before joining the faculty at Walla Walla Community College in 2001. Julianne teaches courses ranging from beginning algebra through differential equations at WWCC. Through active learning and the strategic use of technology, she strives to guide students toward a deeper understanding of mathematics.William Briggs was on the mathematics faculty at the University of Colorado - Denver for 23 years, after teaching at the University of California at San Diego and Clarkson University. He received his BA in mathematics from the University of Colorado and his MS and PhD in applied mathematics from Harvard University. He taught undergraduate and graduate courses throughout the mathematics curriculum, with a special interest in mathematical modeling and differential equations as they apply to problems in the biosciences. He has written a series of calculus textbooks and a quantitative reasoning textbook, Using & Understanding Mathematics; an undergraduate problem-solving book, Ants, Bikes, and Clocks; and two tutorial monographs, The Multigrid Tutorial and The DFT: An Owner’s Manual for the Discrete Fourier Transform. He was the Vice President for Education of the Society for Industrial and Applied Mathematics (SIAM), a University of Colorado President’s Teaching Scholar, a recipient of the Outstanding Teacher Award of the Rocky Mountain Section of the Mathematical Association of America (MAA), and the recipient of a Fulbright Fellowship to Ireland.
