Interesting, the closure of the math tag is missing the / in the docie e^x = \sum_{n = 0}^{\infty} {x^n \over n!} = 1 + x + {x^2 \over 2!} + {x^3 \over 3!} + {x^4 \over 4!} + \cdots

Is the relationship (7/5) * (pi/e) exact, or is it an approximation? --Sven 10:19, 22 Aug 2006 (NZST)
- I had always thought it was exact, but....
#!/usr/bin/perl use Math::Trig; print 7*pi/5/exp(1); print "\n"; print ((1+sqrt(5))/2); print "\n"; |
- gives...
