F(X)=(e^1/x-e^-1/x)/(e^1/x+e^1/x)如何F(X)=(e^1/x-e^-1/x)/(e^1/x+e^1/x)如何F(X)=(e^1/x-e^-1/x)/(e^1/x+e^1

F(X)=(e^1/x-e^-1/x)/(e^1/x+e^1/x)如何
F(X)=(e^1/x-e^-1/x)/(e^1/x+e^1/x)如何

F(X)=(e^1/x-e^-1/x)/(e^1/x+e^1/x)如何
F(X)=(e^1/x-e^-1/x)/(e^1/x+e^【-】1/x)
=(e^2/x-1)/(e^2/x+1)
=1-2/(e^2/x +1)

F(X)=(e^1/x-e^-1/x)/(e^1/x e^-1/x)如何 化解
F(x)=e^2/x 1-1-e^-2/x
F(x)=e^2/x-e^-2/x.
