**Note:**

Thanks to * Richard Hoang* for pointing out that in Q3aiii the sharp point at

*x*= 0 should be a local minimum turning point, and the maxima should be closer to

*x*= +/- 2 than 0.

Thanks to * Andrew Badawy* for pointing out that Question 2d asked for arg(z-1) in [-pi/4, pi/4], but arg(z) in [-pi/4, pi/4] was sketched.
