Hello,

I have finished recently this video for presenting the essential meaning of Integration:

What do you think?

hi peter010

You have done a good job. A simple example helps any student to see easily what is happening before they meet much more complicated examples. I like the way you have highlighted the text as you speak. This must be a great help to any for whom English is not the first language.

Defining integration as a summation process is the way I would do it too. It is possible to prove that the area under a curve gives the same result so I would see this as a consequence of integration rather than another way of defining it. When I was at school my maths teacher said the proof was too hard and 'glossed' over it. But I looked it up and I don't think it is that tough.

Thanks indeed mr.Bob for this neat comment. I believe that Visual materials can abstract thousands of words and a lot of time!
