x = input() s = x.split(',') a = int(s[0]) b = int(s[1]) n = int(s[2]) s = 0 h = (b-a)/n func = lambda i:(1/(a+1+((i-1)*h))+(1/(a+1+i*h)))*h*0.5 for i in range(1,n+1): s += func(i) print('s={:.5f}'.format(s)) “”" 本关任务：编写程序求f(x)= 1/(1+x)​在[a,b]上的定积分

x = eval(input()) n = 1 sn = 0 while sn<x: an = 1/(2*n-1) sn += an n += 1 n = n-1 sn = sn-1/(2*n-1) n = n-1 print("y={},n={}".format(sn,n)) “”" 本关任务：已知y=1/(2*n-1)的前n项和 ,编写程序,实现如下功能： ①从键盘输入一个数x,当y<x时的最大n值。 ②与①的n值对应的y值。 测试输入：3 预期输出：

n = int(input()) x = 1 s = 0 a = 1 b = 1 while x < (n+1): y = a/b s = s + y x = x + 1 b = b + x print("s= {}".format(s)) “”" 本关任务：编写程序,输入n，求表达式的值，表达式如下: 测试输入1：100 预期输出1：s= 1.9801980198019795 “”" ...
