- (iv) Further Examples of Practical Technique
- a) exists for .
Namely, ,
but is not a polynomial unless
is an integer.
- In typical integration formula
The error is .

- Clearly this numerical procedure doesn't work if
even though integral well defined as
infinite, but
**I**well defined. - We could use an ``open'' formula which does not involved but even then, errors will be large. For example has error something like where in range . If , implies that error is for each interval.
