Title: Integrator y= ∫ f(x) dx, enter a function and the integral will be calculated!

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 $\int f(x) dx$.

Prof Hwang can you explain please this project
I try understand is calculate sin only
Could you explain about simulation please
Thanks  :)

What i mean he calculated FX sin only
Could you prof explain simulation by simple description
For me understand and translation  this description to portages
Thanks

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.

Now i understand prof yesterday me and teacher of mathematics try understand but  ???
How ever prof you the best  :)
Thanks
