As a pure math student I have to say this wasn't my favourite class, but I have to acknowledge that Johanna still was a very good teacher and could (and did) answer all questions. The course was well organised. All tutors were knowledgable but some didn't really know how to teach.

This subject was very interesting! I feel like a lot of students in the physics/applied maths stream take this but it is not at all only for them. There is heaps of pure flavour in the content, and as a pure mathematics student doing this subject really inspired me to look at the physical world for very interesting mathematical problems. I would recommend to anyone that has a slight interest (and is up for a bit of a challenge).

Hard subject that was taught differently to previous maths subjects (no room on the lecture slides for examples and annotations, no solutions to the problem booklet) and you really had to concentrate every single second to avoid becoming lost. Some parts probably could have been explained better. Nevertheless the assessments are fair and use lecture content well. There were also more practice exams with solutions than any other subject I've seen, and although the exam is long and tedious, it's not horrible and I probably could have gone a lot better if it was a week later and I studied more.

Hard subject, but very interesting and so very rewarding. If you love math and loved vector calc, you will love this one too. One tip, do NOT lose concentration during lectures, 5 min lost in your mind or instagram and you are doomed if you don't watch the lecture again. Concepts are not hard to grasp, however they might be a bit hard to apply at first, but if you do practice questions you will quickly find the pattern and realize is is the same thing over and over again with different values. Questions are very long, some of the longest I have done in Math so far, so make sure you don't make a mistake in the middle, but finishing it is very satisfying. I do recommend. (PS: This subject requires you to remember all prerequisites and math you have taken before: Calc 2, Linear algebra and Vector calculus are foundation for this subject)

The content of this subject is somewhat interesting. I found the Wronskian/ Abel's Theorem to be a surprising and fascinating result giving a relation between different solutions. Unfortunately much of getting a good mark in the subject revolves around being able to quickly do hard and tedious integrals - i.e integrate by parts, especially for fourier series. Very little is dedicated to understanding where things came from e.g deriving Abel's Theorem, where Fourier comes from, where Laplace Transforms come from as well as interpreting the results of a PDE solution where instead the focus was purely on robotically solving the long tedious PDE. The subject was smoothly run with no hiccups in assessments or assignments and found the tutes to be pretty helpful. Also, thought the new lecturer was rubbish.

Very harder than Vector Calculus, Differential Equations took a different level compared to Calc 2. The lecturer David taught very fairly discussing the topics across from first order to higher order equations including Laplace Transformations!!! However the exam i took had 10 questions a lot longer than the previous exams i could able to complete and check all of them in time. But barley pass this subject. Ignore the additional resources if you can manage your timing right I will endure this subject throughout the semester *unless you go to consultations or your tutors!!!

Well organised throughout the semester, lecturer was incredible, assignments were tedious but rewarding, however the final exam was MUCH more difficult than previous papers this year...

Note that this subject has a new lecturer, and has been made quite a bit easier than when Barry was lecturer. Don't be fooled though, this is still a tough subject that will require a fair amount of work. The hardest parts from the old course are left out as the new lecturer said he felt it was too difficult without having done Complex Analysis first. The lectures WERE recorded this year but I would still recommend going to all lectures. As far as content goes it was quite interesting stuff but it was a bit surprising that it didn't really follow on much from Vector Calc, and used a lot of Linear Algebra stuff, especially early in the semester, so it might be a good idea to revise some of that. The subject might frustrate those who enjoy more Pure maths type things as this subject is very much an applied maths/mathematical Physics subject. Overall though, a pretty good subject.

Very, very difficult. But extremely rewarding. If you make it through with an H1, you will have achieved a new level of mathematics, and life will never be the same. Take the challenge. Work hard. Become amazing. You can do it.

Very difficult and demanding subject. Perfect for students who love maths and like to study a lot. Lecturer makes it entertaining but doesn't record lectures. Good luck.
