Wolfram, the company that brought you Mathematica, introduced a great new web service called Alpha.
Need a calculus equation derived? Enter it in. (for example: x^2 sin(x))
Your "results" include:
Your "results" include:
- The equation plotted
- Alternate forms of the equation
- The roots of the equation
- Series Expansion
- Derivatives, Integrals
- Maximums and Minimums
- Series Representation
- Integral Representation
It's a cool tool for calculus students everywhere. However, the wonder does not stop here. The "Knowledge Engine" is pretty intuitive:
Alpha can compare stocks: Entering 2 stock quotes will give you a table with all the necessary financial data for each company: Income, revenue, P/E Ratios, dividends, and side-by-side comparisons of cash flow statements.
Enter in a city, and get statistics.
Type in a date: Alpha calculates the time since that date, the sunrise/sunset times on that date at your current location, etc.
Thanks to Alpha, I now know that over the past 5 years, Apple's stock has provided investors with a 819% return. Also, there are 1.5x10^25 molecules of water in 356ml of water. Cool!
