Help about tanh(X)=T . e^(jf)

Help please.

I have the equation tanh(X) = T . e^(*j*f)

tanh - is hyperbolic tang.

X is complex number X = a + *j*b

T.e^(*j*f) - is a known complex number = T.cos(*f*)+*j*.T.sin(*f*)

I need clear decision for a=? and b=?

a - real part

b - imaginary part

only like function of *T* anf *f*.

Yes, but the result is very complex. And is not clear. **a** and *b* are rows.

In the first post you said *is a complex number* and now you say are rows. I don't understand. Could you reword the problem?
