AAAA - BBB __________2BB7 AAAA+BBB+CC+D=2002求A.B.C.D是多少? AAAA乘以B-BBB=3000,那么A乘以B=? AAAA+BBB+CC+D=2002求A.B.C.D是多少? ~~~~aaaa~~~~ .aaaa aaaa 1/(a-b)-1/(a+b)-2b/(aa+bb)-4bbb/(aaaa+bbbb)+8bbbbbbb/(bbbbbbbb-aaaaaaaa) bbb是什么 BBB怎么样 bbb是什么? aaaa啊啊 aaaa快点. aaaa这是很么 刚起走aaaa 在MATLAB里用数值画的曲线怎么求其交点值并让其值在图上显示出来AA=mean(A);BB=mean(B);CC=mean(C);AAA=std(A);BBB=std(B);CCC=std(C);AAAA=sort(A);BBBB=sort(B);CCCC=sort(C);plot(AAAA,normpdf(AAAA,AA,AAA),'r');hold on ;plot(BBBB,nor 学案bbb 社会学是什么?bbb
