About WebGraphing.com There is a substantial research literature that suggests learning in mathematics can be achieved by reading workedout examples. WebGraphing.com goes one step further: it strives to jumpstart students to learn mathematics by reading workedout examples of their own choosing. Unlike other web sites dedicated to mathematics, WebGraphing.com delivers realtime, stepbystep answers to challenging mathematics problems. There are a number of unique, patented features that make our calculators easier to use and more powerful than other graphing calculators. In comparison, our calculators take more of the grunt work out of demanding computations that contribute very little either to student learning or teacher productivity. WebGraphing.com began operations in 2003. On average, we receive over 8,000 daily visitors from over 100 countries. We currently have over 150,000 members comprised of students, teachers and parents. This represents a lot of learning of mathematics, checking answers, copying publicationquality graphs, and mathematics exploration. 

Professor Cherkas has received numerous grants and written many articles in mathematics and mathematics education, including an article related to graphing: “Finding polynomial and rational function turning points in precalculus,” which appeared in the International Journal of Computers for Mathematical Learning, Vol. 8, No. 2, 2003, 215234 Computer Math Snapshots Section. He has also written a book on using technology to learn precalculus: “Precalculus: Anticipating Calculus Using Mathematica® Labs,” 2002, Jamaica, New York: Euler Press. More recently, he is a coauthor (with Dr. Rachael Welder) of the chapter Interactive Webbased Tools for Learning Mathematics: Best Practices appearing in the 2011 IGI Global publication, Teaching Mathematics Online: Emergent Technologies and Methodologies (edited by Dr. Angel A. Juan, Maria A. Hertas, Sven Trenholm and Cristina Steegman.) Professor Cherkas welcomes any feedback and suggestions through the contact form.
