Does there exist an analytic function $f:\mathbb{C}\rightarrow\mathbb{C}$ such that $f$ is bounded on both real and imaginary axes?
According to Liouville's theorem the function must be constant but I am confused that any bounded function $f$ on $\mathbb{C}$ must be like $f(z)=c$ where c is a constant. I am convinced that it must be bounded with respect to one axis but how about other axis. For example, $f(z)=1$ then it is bounded w.r.t real axis but how about imaginary axis? Question may be easy for other but I am unable to visualize it .
