Determine whether the given functions are harmonic or not. If they are harmonic functions, find for each a function $f(z) $ of which the given function is the real part and show that the function $v(x, y) $ (which you find) also harmonic a. $u(x, y)=-cosh y \cos x$ b. $u(x, y)=e^{x} \cos y+e^{y} \sin x$ CS.
