Integration
Why do we hafta integrate?
Divide/conquer technique:
- Divide the object (or problem) into chunks
- Come up with an integration variable which both
- labels the chunks ($x$), and
- quantifies the size of each chunk ($dx$).
- Write the quantity to be added up in terms of the integration variable and the differential. Use ratios to figure this out...
- Set appropriate integration limits on your integration variable.
- Solve the integral!
