Registed user can get files related to this applet for offline access.
Problem viewing java?Add http://www.phy.ntnu.edu.tw/ to exception site list
If java program did not show up, please download and install latest Java RUN TIME

This applet allow you to enter f(x) and range of x, and the program will calculate the integration for f(x).
Drag the mouse inside the simulation region, will show the correspond y=f(x) and it's integral \int f(x) dx.

The above simulation will calculate \int_{x_i}^{x_f} f(x) dx
where f(x) can be any function of x
You need to specify the range of integration x_i,x_f
The default is f(x)=sin (a*x) to show that user can enter methematic function
However, it can be changed to f(x)=x+0.5*x*x or any other form of polynomial.
