求椭圆[tex=7.143x1.286]rhr0y16qUlOgXhsFYHCPn7t5Vc4ECgWhG1LsxNakX6I=[/tex]上纵坐标最大和最小的点。
举一反三
- 求[tex=7.143x1.286]rhr0y16qUlOgXhsFYHCPn7t5Vc4ECgWhG1LsxNakX6I=[/tex]上点的纵坐标[tex=0.571x1.286]Hz6y44ELFVLLNrLVhO3CQA==[/tex]的最大值,最小值 .
- Public Sub Proc(a%( )) Static i% Do a(i) = a(i) + a(i + 1) i = i + 1 Loop While i < 2 End Sub Private Sub Command1_Click( ) Dim m%, i%, x%(10) For i = 0 To 4: x(i) = i + 1: Next i For i = 1 To 2: Call Proc(x): Next i For i = 0 To 4: Print x(i);: Next i End Sub A: 3 4 7 5 6 B: 3 5 7 4 5 C: 2 3 4 4 5 D: 4 5 6 7 8
- 下面说法错误的是( )。知识点:列表推导式 A: dict([(x, x**2) for x in range(6)]) 创建的字典是{0: 0, 1: 1, 2: 4, 3: 9, 4: 16, 5: 25} B: [[x*3+y for y in range(1,4)] for x in range(3)] 创建的是二维列表 [[1, 2, 3], [4, 5, 6], [7, 8, 9]] C: number = [-2, 4, 6, -5]string = 'ab'z = [(i, j) if i>0 else (-i, j) for i in number for j in string]这段代码创建的列表为[(2, 'a'), (2, 'b'), (4, 'a'), (4, 'b'), (6, 'a'), (6, 'b'), (5, 'a'), (5, 'b')] D: ' '.join([i for i in range(1,11)])的运算结果为字符串'1 2 3 4 5 6 7 8 9 10'
- 求下列投影点的坐标:(1) 点[tex=4.0x1.357]mOrLwYmlp1M0w9+kSXRp+g==[/tex]在平面[tex=6.143x1.214]o5o0EBSefct5XSmokDzGbw==[/tex]上的投影点
- 有代码片段:function f(y) {var x=y*y;return x;} for(var x=0;x< 5;x++) {y=f(x);document.writeln(y);}输出结果是( )。 A: 0 1 2 3 4 B: 0 1 4 9 16 C: 0 1 4 9 16 25 D: 0 1 2 3 4 5
