练习3-65
原文
Exercise 3.65. Use the series
ln2 = 1- 1/2 + 1/3 - 1/4 + ……
to compute three sequences of approximations to the natural logarithm of 2, in the same way we did above for . How rapidly do these sequences converge?
代码
(define (ln2-summands n)
(cons-stream (/ 1.0 n)
(stream-map - (ln2-summands (+ n 1)))))
(define ln2-stream
(partial-sums (ln2-summands 1)))感谢访问，希望对您有所帮助。 欢迎关注或收藏、评论或点赞。
