I am emailing a link of this to everyone on the class list every week. If you are not receiving these emails or want to have them sent to another email address feel free to email me at jpmccarthymaths@gmail.com and I will add you to the mailing list.

Homework

The closing date is tomorrow three weeks: that is 11 April at 2 pm. Work handed up late will be assigned a mark of zero.

Week 11

More on complex numbers including De Moivre’s Theorem and taking roots.

Week 12

On Monday we will talk a little bit more about taking roots of complex numbers and also do an actual example. This will wrap things up in terms of lectures.

On Wednesday we will have an additional tutorial so that we can get through some more examples. As normal there will be a tutorial on Thursday (and a review lecture after the break).

Exercises

For the Week 12 tutorial you should look back over the exercises in general.

If you are happy with them then maybe you could have a look at some of the harder applied problems — which are definitely not examinable but will test your understanding.

If you are doing abstract algebra Q.1 is a good, tough exercise. Q. 6 (h) is another good question bringing in complex numbers.

Math.Stack Exchange

If you find yourself stuck and for some reason feel unable to ask me the question you could do worse than go to the excellent site math.stackexchange.com. If you are nice and polite, and show due deference to these principles you will find that your questions are answered promptly.
