Hi Folks,

Use the properties of complex differentiation to calculate f'(z) for the following

a) $\displaystyle (3-2i)z+4i$, b)$\displaystyle z^3-(2+i)z^2+(1+3i)z-1$

Not sure how to tackle these. My attempt -

Using the property similar to real values differentiable functions $\displaystyle \frac{d f(Az)}{dz}$ where A is a constant we have for

a) (3-2i)

b) 3z^2 -2z(2+i)+(1+3i)...?

Thanks
