I enjoy connecting with someone who comes to me struggling with a homework problem and goes away with a new understanding. If you are struggling with something in algebra, trig, first 4 semesters of calculus, abstract algebra, or real analysis, or if you just like to gab about any of these subjects, consider emailing me by clicking here . I am currently working on an online calculus tutorial, much of which is already on line. You can see the what's currently available by clicking here . If you would care to kibbitz on the development of this effort, you can email me.
New units come on line at a rate of about one per month.
I have prepared a DOS program that is a great aid in doing some math problems, as well as physics and chemistry problems. It is a complex number calculator with dozens of functions from those as mundane as square root to those as abstract as Jacobian elliptic functions. There is a help message on each key that gives details about it, including accuracy, identities, and uses of the function. In addition, there are scads of online physics constants, as well as a periodic table with atomic weight and plenty of physical, chemical, thermodynamic, and isotope data on each element. Be sure to read the readme file carefully before installing.
