Matrix Editor	mathbasic83p	Rob Sears	2003-03-31 00:00:00	This program allows a user to perform the elementary row operations on a matrix and it displays the modified matrix after each step. A real time-saver for students in Elementary Linear Algebra.	No
Newton's Method	mathbasic83p	Rob Sears	2003-04-02 00:00:00	This program implements Brandon Sterner's "Symbolic" utility (included in this zip file) to calculate the roots of higher-degree polynomials. Basically, it'll find/approximate the y-intercept of any function. A must for Calc I students.	No
Riemann Sums	mathbasic83p	Rob Sears	2003-04-02 00:00:00	Uses brute force and the Riemann equations to find the area under a curve between two points. User inputs the function, two points, and the number of rectangles to calculate. The program then uses the Riemann summ equations to calculate a Left Hand sum, a Right Hand sum, and a Midpoint sum. It then averages those three to calculate the Riemann sum. A must for Calc 1 students	No
Randgen	utilbasic83p	Rob Sears	2003-04-02 00:00:00	This program requires a bit of explaining: When taking a test like the SAT, ACT or SAT II partial credit is deducted for wrong answers and no credit is given for blank answers. However, if you can eliminate some of the obviously wrong answers, then you can use the Expected Value Theorem of statistics to determine your chances of gaining points by guessing the right answer. Thus, if you are taking such a test and you find that you come across a problem to which you just don't know the answer, you can eliminate the blatently-wrong choices and then use this program to randomly select one of the remaining choices (provided that calculators are allowed on the test). Program returns a random value for the answer you should select along with a probability of you gaining points on the test.	No
