-0-0-0（1）a正极,b负极,c阴极,d阳极,e阳极锌,f阴极铁c显红色,氢氧根增多,cd为电解饱和食盐水,c:2H++2e=H2(气体符号),f:2Cl--2e=Cl2(气体符号),所以a正极b

(0(0(0范围应该是:(0,π]∵x∈(0,π]设t=sinx,t∈(0,1]y=sinx+4/sinx即：y=t+4/tt∈(0,2]上是减函数∴当t=1时,即x=π/2时y(min)=1+4=5

-0--0--0-吃惊吧--

>0>0>0

:0:0:0换元令t=sinxt∈(0,1)y=t+2/t这个是对勾函数,在（0,1)上递减t=1时,y=3所以y=sinx+2/sinx的值域（3,+∞）令t=sinx因为0所以t∈(0,1)y=t
