Math Help Sites
Here are a several sites that offer help in mathematics. All of these sites offer "live" help. Several of these sites operate through email and other operate through a forum system.
- MathNerds A free math help site. Be forewarned, they won't just work your homework for you (and that's a good thing)! They will expect you to tell them what you've already tried and what you don't understand.
- Dr. Math Another free help site and like MathNerds won't just work your homework for you!
- Free Math Help This is a forum in which you can get help in Algebra, Geometry and Calculus. You need to register, but the registration is free.
- S.O.S Math Forum S.O.S Math's forum for getting help for a wide variety of classes. In order to post a question you'll need to register, but it's free.
- Get Homework Help This is a really nice site that offers help in a large number of subjects (not just math!). In order to post a question you'll need to register, but it's free.
- Homeworkhelp.com This site has both help services as well as software.
Online Tutorial Sites
Here are a variety of sites that have online tutorials and/or lessons. Any tutorial sites listed here similar to mine in that they have online resources but may not necessarily have "live" help as the sites listed above have.
Math Information Sites
Here are a variety of sites that contain a wealth of information about a variety
of math topics.
- Purplemath This site is a great site with lots of resources and links relating to Algebra.
- The Dr. Math FAQ This is a nice site that answers to a lot of the frequently asked questions in math.
- Math World Here is an online
math encyclopedia.
- Cut the Knot! This site contains solutions to quite a few challenging problems including the 12 coins (or bags of gold) problem.
- Online Glossary of Technical Notation A glossary for mathematical notation.
- The Mathematical Atlas This site gives descriptions of math of the the various areas of modern mathematics.
- S.O.S Mathematics This site has information about a large variety of topics from Algebra to more advanced math course.
- Geometric Formulas Here are a variety of geometric formulas from Dr. Math.
- Educational Resources A nice site by Avraham Goldstein which contains a variety of free resources for help in a variety of areas.
Online Exercises and Problems
Here are some sites that have some excesses for you to practice on.
- Algebra Help Worksheets Here are nice set of worksheets on Algebrahelp.com
- EdHelper This site can generate practice problem sets over a wide range of Algebra and Trigonometry topics.
- S.O.S Practice Exams Here
is the S.O.S practice exam page. They have practice exams for topics ranging
from Algebra to Calculus to Differential Equations.
Software
Here are are some links to some nice software packages that you may find useful. Some of the software is free and others must be purchased.
- Math 911 This is a nice program for help in Algebra.
- Equation Grapher This is a nice (and free) program for graphing basic graphs. They also have a program that can do regression analysis.
- Peanut Software This is a nice collection of free programs. Included are programs that will do basic statistics computations, discrete math computations, matrix computations, graph geometric figures, graph fractals, and a general function grapher.
- Graphing Calculator This
is a really nice graphing program. It is capable of graphing in 2 or 3 dimensions
and it capable of dealing with all the standard coordinate systems that you're
liable to run across in a calculus course. The only drawback is that it does
cost, but it's much cheaper than other programs with it's graphing capabilities.
- Maple This is the program that I used to generate many of the graphs on this site (or at least the base graphs, many of the equations where later added using Photoshop....). This is a program that is capable of doing just about anything that you could ever want to do mathematically. It is even capable of doing some graduate level mathematics. The full product is VERY expensive, but they do sell a student version as well.
- Mathmatica This
is another program similar to Maple. I've not used it in years and so I
can't really attest to it's capabilities. The full version is again VERY expensive,
but they also sell a student version.
- Matlab This is a really nice program for doing numerical computations. It is used in a wide variety of engineering and mathematics applications and is probably one of the most well known/used programs for numerical computations. It is however quite expensive.
- Scilab This is a essentially a Matlab clone. It may not be capable of all the really advanced things that Matlab is, but for most of the everyday applications it is just as capable as Matlab. One of the nice features of Scilab is that it is free.
Online Calculators
Here are a variety of online resources that will do some automatic calculations
for you.
- QuickMath An online calculator for a variety of Algebra problems.
- Webmath.com This site has will do many types of computations online from Algebra to Calculus. The site will not only give answers but the steps required to get most of the answers.
- Algebra Help Calculators Here are the calculators at Algebrahelp.com.
- Calculator.com This has just about
every kind of basic calculator that you can think of, including most of the
various kinds of conversion calculators that you'd ever need.
- Automatic Calculus and Algebra Help This
site has some can compute a variety of Algebra and Calculus problems.
- Statistics Calculators Here are a variety of statistics calculators.
- Calculator City This site has a large
variety of calculators for Algebra, Trigonometry and Calculus classes. They
also have some other calculators such as financial, astronomy, chemistry and
physics calculators.
- WebGraphing.com This site some nice online graphing calculators. They can do 2D and 3D equations as well as systems of equations and inequalities. They also have a forum to help students in Algebra, PreCalculus and Calculus. There is a small fee to access some of the more advanced features.
- Calc5 An calculator with a Google Gadget version.
Miscellaneous
Just a few sites that don't fit into any of the other areas above.
- PDF Pad A variety of graph papers that you can print for free.
- Here is
another source of graph paper.There aren't
as many kinds here as the previous links, but these include nice headers
for you to place information and they are free.
- How do I Compute my Grade? A really nice page showing you how to basic grade computations. In particular they answer the age old question of "What do I need on the final to get a grade of X?".
- How will this help me in "real" life? That question is the bane of all teachers. Go to this site to get a jump start in answering this question.
- The Free Information Society This is an excellent site devoted to free information. They have lots of information and you should check it out if you get a chance.
