Hey,
Using exponential definitions, show that
tanh(2x)= (2tanh(x))/(1+tanh^2(x))
Please help. Thanks

Start by writing down the exponential form for $\displaystyle \tanh(2x)$ then do the same for the right hand side. Now simplify what you have for the right hand side and with luck you will find that it is the same as you had for $\displaystyle \tanh(2x)$.
So try this and report back if you get stuck.
