Welcome This is a Web-based Community for the development and sharing of an assorted variety of mathematics content. It is intended to serve as a virtual meeting place for the exchange of ideas pertaining to mathematics courses at UTSA. There are many resources available beyond the News Articles listed below. Especially important is the Forum section that you can select from panel at left labeled Modules. Thank you and enjoy.   –Crissy Ruffo Continuity: Stanley Lab Notes 1-30-08 What does it mean for a function to be continuous? What is the Intermediate Value Theorem (IVT)? Download Stanley-Lab-Notes-1-30-08.pdf Posted by crissy on Wednesday, January 30 @ 17:01:15 CST (8 reads) (comments? | Continuity | Score: 0) calculus: Calculus I Optimization Problem Consider the following problem: A farmer with 750 ft of fencing wants to enclose a rectangular area and then divide it into four pens with fencing parallel to one side of the rectangle. What is the largest possible total area of the four pens? Here is a SAGE program to estimate the answer using both the animate and the @interact commands. Then I settle the question using calculus methods.

Designed to help visualize the relationship between a function and it's first and second derivatives.  Here is an example of what the output looks like: View HTML page: Plot Tool Sage.html Download Workshseet: Plot Tool.sws Visit Forum Post:  Plot Tool Posted by crissy on Monday, July 14 @ 16:02:30 CDT (11 reads) (comments? | graphing | Score: 0) numerical: Nonlinear One Variable Equation Numerical Solver This worksheet collects together 6 separate SAGE scripts, based on classical algorithms, designed to find numerical solutions to the equation f(x)=0, when x cannot be explicitly solved for. Each of the scripts can be found in the other worksheets in this site.
