Exercise 1.15 # The sine of an angle (specified in radians) can be computed by making use of the approximation $sinx≈x$ if x is sufficiently small, and the trigonometric identity $$ sinx=3sin\frac{x}{3}−4sin^3\frac{x}{3} $$ to reduce the size of the argument of sin. (For purposes of this exercise an angle is considered sufficiently small if its magnitude is not greater than 0.1 radians.) These ideas are incorporated in the following procedures: ...

...SICP 练习1-14 # 题目 # Draw the tree illustrating the process generated by the count-change procedure of Section 1.2.2 in making change for 11 cents. What are the orders of growth of the space and number of steps used by this process as the amount to be changed increases? 使用『找零钱』算法，用5枚硬币找出来11美分，即$f(11,5)$，绘制这个算法的过程，并且思考在这个算法中，对于空间复杂度和时间复杂度的计算方式。 (define (change amount coins) (-> exact-integer? (listof exact-integer?) exact-integer?) (define (cc amount kind-of-coins) (cond [(= amount 0) 1] [(or (< amount 0) (= kind-of-coins 0)) 0] [else (+ (cc amount (- kind-of-coins 1)) (cc (- amount (list-ref coins (- kind-of-coins 1))) kind-of-coins) ) ] )) (cc amount (length coins)) ) ;; 使用方式 (change 11 '(1 2 5 10 50)) 转载 & 学习 # https://sicp-solutions. ...
