# prove that if $|f(z)|\geq |z|+|\sin(z)|$ then it cannot be an entire function

Problem: Prove that if $$\forall z \in \mathbb{C}.|f(z)|\geq |z|+|\sin(z)|$$ then it cannot be an entire function.

I thought about claiming that $$f$$ must be a polynomial because it has a pole in infinity, but I stuck why it polynomial cannot satisfy this property.
