设arctan(3/2)=A,arctan(2/3)=B
所以tanA=3/2>0,tanB=2/3>0
又因为A,B属于[-π/2,π/2]
所以A,B都为锐角
tanA*tanB=1,故A和B互余
A+B=π/2
π－arctan(3/2)－arctan(2/3)=π/2

arctan(-2)+arctan(-3)=? arctan(1/3)+arctan(1/2)的值为? 求证：arctan 1/2+arctan 1/5+arctan 1/8=π/4 arctanπ/2＝? 求arctan1/3+arctan(-2)的值 arctan1/3+arctan(-2)的值为求值：sin[1/2arctan(-4/3)] 求arctan1/3+arctan(-2)的值. arctan(A/2)+arctan(A/5)=30 tan(arcsin1/2-arctan根号3)= 3Q y=arctan(2+3^x)求反函数 arctan(e^x-1)^1/2=π/3求x
