Your New Mathematics Online Helper (or near to it) – Wolfram
By: Karan Goel | 23rd October 2009
Wolfram has been in news for being next Google Killer. Well, its not a Google Killer but for sure a killer web application for knowledge based searching. Besides the main knowledge based search functionality, Wolfram also has a dedicated Online Integrator at Wolfram Mathematica section.
Why Mathematica? Because this one integrated system delivers unprecedented workflow, coherence, reliability, and innovation. Rather than different toolkits for different jobs, Mathematica has been built ground-up for more than 20 years to deliver one vision: the ultimate technical application and environment.

It allows you to solve complex integration problems with a click of a button. Just enter your integration string and click the compute online button to see solution in few seconds. Online Integrator at Wolfram is an excellent web service for students and this functionality is also available in download-able version for students (but for a price)!

Wish I had this tool back in 11th grade. Heck, there wasn't even internet back then… The current generation of mathematicians is definitely lucky.
