举一反三
- 下面哪个选项能使集合 S 等价于不能被 3 整除的正整数集合? A: 1∈S;x∈S→2x+2∈S B: 1∈S;x∈S→x+3∈S C: 1∈S,2∈S;x∈S→x+3∈S D: 1∈S;x∈S→3x+1∈S
- 设函数f(x)=x2,0≤x≤1,而S(x)=,-∞≤x<+∞。其中,(n=1,2,…),则S(-1/2)等于()。 A: -1/2 B: -1/4 C: 1/4 D: 1/2
- 根据x的正、负、零的情况把s赋值为+1、-1、0,写作:if(x>0)s=1;elseif(x<0)s=-1;________s=0;
- 设函数f(x)=x2(0≤x<1),而S(x)=bnsinnπx,其中bn=2f(x)sinnπxdx(n=1,2,…),则S==() A: -(1/2) B: -(1/4) C: 1/4 D: 1/2
