- I assume that your answer is using radians? Feynmann of course could
- not calculate things to 100 digits. But he could have solved the problem
- in his head if he did it as degrees (the original problem poser does
- not seem to have specified)

- tan 100 = -5.67128
- tan 1000 = -5.67128
- tan 10000 = -5.67128, etc.
