Euler's number - derive 'e' using Java

//deriving 'e' or Euler's number. The equivalent would be (1+1/n)^n on a spreadsheet or using LaTex.

public class MathHell5 {

public static void main(String[] args) {
for (double d = 0; d <= 1000; d++) {
System.out.println(" ");
System.out.println(Math.pow((1+1/d),d));
}
}
}
//pow(double a, double b)
//Returns the value of the first argument raised to the power of the second argument.

Desmos - Maths Chrome App

Desmos!



y-sin 2x
h=sin 3g

The above graphic was created using the Desmos Chrome Web App. Input your functions and it will draw the graph for you. Very nice to use and intuitive etc.

Currently, I'm testing out the Chrome Apps that can do useful things with Maths. Also, trying to test out some of the Mathematics software available in the Linux ecosystem. There is so much Maths software in the Ubuntu repositories!

Desmos seems to be purely online but there is another graphing package which is available as a web app and as a full Linux desktop package - Geogebra.

Geogebra will also help you to draw perpendicular bisectors and regular polygons along with functions too.
The graphic above was made in Geogebra - good fun and also intuitive.

Enjoy!

Real equations


Created using Daum Equation Editor and Scribblr.
Daum uses LaTex to generate nice equations.
Got the background on Flickr via Scribblr.com

Scribblar + Daum Equation Editor = Online Maths Tutoring System

Daum Equation Editor
My Scribblar page

Daum enables you to create really nicely formatted equations. It's a Chrome App so is easy to get if you are running Google Chrome browser (or Chromium on Linux etc).

Scribblar is a system where you can share a screen - you can draw diagrams, type/chat text and insert equations using the inbuilt LaTex editor (or use Daum to generate the LaTex for you).

Example page with a 'made up equation',

And a screenshot of the same.
