# Intergration watch

1. I am trying to understand how integration works. I checked text books but they don't offer the basics. For example what process would you need to integrate y=x, is it integration by parts?
2. Integration is the inverse process to differentiation. So instead of multiplying by the index and reducing the index by one, we increase the index by one and divide by the new index. For example, becomes . The appears because the derivative of any constant term is zero.

Differentiation is finding the gradient of a curve. Integration is finding the area between a curve. It is defined as the limit of riemann sums (for definite integrals). That is, make a bunch of rectangles to estimate the area of the graph, then send the width of each rectangle in the limit to 0 and sum them all up. One short cut in integration is:

for .

Teach me for trying to be clever. Distressed to see that the powers that be are trying to get rid of the circumflex. Is nothing sacred?

Don't worry - I've probably made a mistake somewhere too. Still, I can see that when it comes to modern developments in the French language, you clearly know your ognons.

But however are French people going to indicate exponentiation now? - that's what really worries me.

C'est le nivellement par le bas. Vraiment ça me soûle
