Math Warehouse's homework forum is switching over to a new and improved system and a new domain-- www.painfreehomework.com. Like  www.mathwarehouse.com/ask, the goal of the new site will be to help students connect with experts for homework help.

There are many changes and lots of improvements on the new site.  The biggest change that you should know about is that you will be asked to purchase answers to your questions. However, as a way to thank you for your membership at mathwarehouse.com  and to encourage you to give our new site at www.painfreehomework.com a try, we are offering a FREE COUPON that will supply you with some virtual money for the new site. 

This coupon will let you continue to get answers to your homework questions for free! (for however long as the $10 coupon lasts!)

There are no  strings attached--no membership fees, no subscription requirements, no commitments at all. You can use this coupon to test drive our new site for free.

You will need to re-register. We didn't think users would want to be automatically re-registered for a new site.

 You must use this coupon when you sign up,  just make sure that you use the following coupon code : mathwarehouse1 .   You must signup by May 1st to be able to use the $10 coupon.

Online Graphing Calculators and Apps

Most U.S. students know about the Texas Instruments Graphing calculators! They are powerful and can do a lot of great stuff including graphing equations, work with matrices ,  perform statistical analysis and much more. Heck they can even work with complex numbers!  and the TI-89 is so powerful that many standardized tests do not allow test takers to use them--the 89 can do a lot of Calculus for you--take derivatives, use the power rule and much more. It's like Wolfram Alpha in a small box !

However, with the rise of the the internet most of these features can now be found online and usually for free! Here' s a list of the best resources that I know

Online Graphing Calculators

• Meta  Calculator - basically  a free virtual Texas instruments calculator 
• Archimy- great 3-d Graphs, even if user interface is a little bit rough around the edges
• Wolfram Alpha - Like a TI-89 on steroids! This baby can do pretty much anything that you might want!
• Google.com - Yes, Google.com can now graph equations! Just type sin(x) in the search bar and you'll see what I mean!

All three of these are very powerful , free. In the end, they can actually do more than your TI calculator at home can probably do!
