举一反三
- 当函数是以为周期的偶函数时,则的傅里叶级数称为( )。a0a0a1b1876d02aa4c0cf473feb19962.pngeb66bf841630b81f19fcfdb4ef302350.pnga0a0a1b1876d02aa4c0cf473feb19962.png
- 已知a、b、c∈R,函数f(x)=ax2+bx+c.若f(0)=f(4)>f(1),则( ) A: a>0,4a+b=0 B: a<0,4a+b=0 C: a>0,2a+b=0 D: a<0,2a+b=0
- 已知(AL)=80H,ADD AL,0A0H指令执行后, CF和OF的值是( ) 。 A: CF=0 OF=1 B: CF=1 OF=1 C: CF=1 OF=0 D: CF=0 OF=0
- 已知(AL)=88D,ADD AL,177D 指令执行后,CF和OF的值是( )。 A: (CF)=0 (OF)=1 B: (CF)=1 (OF)=0 C: (CF)=0 (OF)=0 D: (CF)=1 (OF)=1
- 转移指令JNBE产生转移的条件是() A: CF=0 AND ZF=0 B: CF=0 AND ZF=1 C: CF=1 AND ZF=1 D: CF=1 AND ZF=0
