# Real part of $\sinh(z)$

Is it true that for every $z \in \mathbb{C}$

\begin{align} &2\mathfrak{Re}(\sinh z) &= \sinh z + \sinh \bar z\\ &2i\cdot \mathfrak{Im}(\sinh z) &= \sinh z - \sinh \bar z \end{align}

Welcome to MSE, Michael. We will certainly help you - but to make it in a better way, could you tell what are the confusing points for you? E.g. would you put here how did you derive these formulas? – Ilya Feb 20 '12 at 13:24
It was a step in a solution I was trying to follow. The question itself was about proving a function to be harmonic and finding it's conjugate. Thank you. – Michael Feb 20 '12 at 14:05
