锐角a、b满足:sinb=mcos(a+b)sina,m>0,a+b≠π/2,令y=tanb,x=tana.

a,b属于(0,π/2),满足sinB/sinA=cos(A+B).求证tan(A+B)=2tana,tanb=(sin 已知A,B为锐角,SinA/SinB=Cos(A+B)求TanA的最大值 已知A,B是锐角,A+B≠π/2,且满足3sinB=sin(2A+B)求证tanB≤2^(1/2)/4 已知A,B是锐角,A+B≠π/2,且满足3sinB=sin(2A+B),求证tanB≤(2^0.5)/4 已知sin(2A+B)=3sinB,设tanA=x,tanB=y,记y=f(x).求证：tan(A+B)=2tanA;求 已知sin(2a+b)=3sinb 设tana=x tanb=y 记y=f(x) 已知sin(2a+b)=3sinb,设tana=x,tanb=y求证：tan﹙a+b)=2tana 在锐角△ABC中,内角A,B,C满足tanA-tanB=跟号3/3(1+tanA.tanB). SINA+SINB+SINC=COSA+COSB+COSC=0,求TAN(A+B+C)+TANA*TANB*TANC 已知tana=根号3(1+m) ,根号3(tanA*tanB+m)+tanB=0 且A B锐角,则A+B= △ABC中,已知(a+b+c)(sinA+sinB-sinC)=3asinB,且(tanA-tanB)/(tanA+ta 设△ABC,3sinB=sin(2A+B),∠A为锐角,1.求证tan(A+B)=2tanA;2.求tanB的最大值以及
