Wolfram|Alpha is a "computational knowledge engine", Basically its a search engine that does math. It can do any math formula. As a matter of fact it can do anything that has to do with numbers. It can also answer regular verbal/text questions. Its a really useful tool to use throughout your school/college career. If only i knew about this last year. Hopefully there is still time for you guys. But seriously... This website is pretty neat.
Example: x^2 sin(X)
Or even calculations: $250 + 15%
Notes:
-Answers questions from complex algebra to the date of Nixon's birthday.
-Free and will always be free
-Theres an app for that.
-The prefect site for anyone one in school. No matter the year.
