Three Questions on Complex Differentiation and the Cauchy-Riemann Equations

In this video we tackle three fairly standard questions that might be asked on the topic of complex differentiation and the Cauchy-Riemann equations. As we shall see, once understood, these questions are nowhere near as difficult as they might appear at first glance.
Note: In question one of this video, we mention a video where we differentiate the complex 'cos z' and 'sin z' - that video is entitled 'Differentiating Trigonometric Identities Cos z and Sin z for Complex z' and can be found at • Differentiating Trigon...
