 ``` 10 December 2001 Vol. 6, No. 50 THE MATH FORUM INTERNET NEWS Fun and Sun Rent-A-Car - Lanius Mathematical Functions - Wolfram | The Grey Labyrinth - Lin FUN AND SUN RENT-A-CAR - Cynthia Lanius An investigation using tables, graphs, and linear functions to solve a real-world problem. The lesson is available in two versions: Print Version http://math.rice.edu/~lanius/Algebra/rentacar.html Java Version http://math.rice.edu/~lanius/Algebra/rentacarja.html This activity was written to align with the Algebra Texas Essential Knowledge and Skills (TEKS). It also aligns with the End-of-Course Algebra Objectives and supports the guidelines in the National Council of Teachers of Mathematics Principles and Standards. http://math.rice.edu/~lanius/Algebra/rentnotes.html From Cynthia Lanius' math lessons, which feature subjects as diverse as infinite series, fractals, cartography, dueling pinwheels, a hot tub (interpreting graphs), and more: http://math.rice.edu/~lanius/Lessons/ -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- MATHEMATICAL FUNCTIONS - Wolfram Research, Inc. http://functions.wolfram.com/ An encyclopedic collection of information about tens of thousands of mathematical functions. The site details the interrelationships between the special functions of mathematical physics and the elementary functions of mathematical analysis, as well as the interrelationships between the functions in each group. Function categories include: - Elementary Functions - Constants - Bessel, Airy, Struve Functions - Integer Functions - Polynomials - Gamma, Beta, Erf - Hypergeometric Functions - Elliptic Integrals - Elliptic Functions - Zeta Functions & Polylogarithms - Mathieu Functions - Complex Components - Number Theory Functions - Generalized Functions All of the formulas are available not only in Mathematica StandardForm but also in MathML and ASCII form.
