If 50g returned -96.581, that means:
1. No symbolic processing used for integration
2. Integration by Simpson rule, thus poor performance (and wrong!)

My mistake, Simpson Rule + Romberg's Extrapolation led to a wrong answer

Code:
Intervals Simpson Rule     Romberg Extrapolation 2         -96.6253287218 4         -96.5838952128   -96.5811329788 8         -96.5813742133   -96.5812072753 16        -96.5812176925   -96.5812072753 32        -96.5812079261   -96.5812072753

Simpson Rule alone will eventually converge: 0.51281 (2048 intervals), 0.5128123250 (32768 intervals)
