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.

## Test 2

Having spoken with Ted, Test 2 — on Laplace Methods — will now be held on Monday 29 April in Week 12 (rather than Week 11). I have a sample ready here — for q.1(a) let $x'(0)=0$.

## Weeks 7 & 8

Plenty of Laplace

## Week 9

Finish off Laplace. I will give ye the Laplace-Mega-Sheet (TM) also.

## More Explanations

Somebody told me the beauty of learning about maths off a video is that you can pause the lecturer. I found these online and I have to say I like these lectures a lot… not many examples but we do them in class even if you seem to think that I don’t!

Ye would have covered lectures 11 to 14 last semester.

Lectures 19 & 20 are relevant for us. Lecture 22 and 23 are where this stuff ends up being really useful (not in MATH7021 unfortunately).

## 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. For example this question on an inverse Laplace transform.

Yes the following table should be A-L and M-Z not A-L and K-Z!
