Thankyou for all of your assistance.

Welcome to Smath Community. Please, do not hesitate.
This document is most precious in several counts:

1. Smath has limited access to "maple".
2. The native Smath Simpson integrator ranges from 15 decimals
to absolute disaster as demonstrated.
3. Simpson integrator supports Romberg Transform,
this example is decently rescued.
4. Wolfram Alpha is a most precious free web companion

For a while, we couldn't access Eric W. integration.
CRC was suing Eric, pretending Eric didn't have Copyright.
St...d CRC, their all stuff is collection/collection/collection...
It toke so long for the Congress to decide whether
π should be 3 or 4, that it was forgotten as 'π' !!!
