The invention of complex numbers allowed to express trigonometric functions through hyperbolic ones in closed form.
Is there possible an extension of real/complex numbers in which logarithms and inverse trigonometric functions can be expressed in terms of exponentials/trigonometric functions and vice versa in closed form?
P.S. I have asked herehere but is seems people there just do not understand the question.
What I am talking about is something like this: $$\frac1\pi\ln \left(\frac{w-\frac{z}{\pi }}{w-1+\frac{z}{\pi }}\right)=\frac1z\cos (2wz)$$
or this:
$$\ln(\sin(w + z)) = 1/z \cos(2 w z)$$
Where $w$ is some element of the extended field, not a complex number. Is this possible?
