Welcome to the wonderful world of ENGG2011A! 



ERG2011A Advanced Engineering Maths (Syll A)


2010-2011 1st Semester





QUIZ 3 - 5 SOLUTION Dec 8, 2010
Here is the Maxima worksheet for your Maxima quiz. LINK Nov 30, 2010

Just for your reference: Laplace transform table or http://en.wikipedia.org/wiki/Laplace_transform


Remark: the function in wikipedia is just multiplied by u(t), it is nothing but the transform holds for t>0. You are not necessary to write u(t) in the function.

I will be in office on Tuesday 1930 - 2030. (No tutorial tomorrow) If you have questions about the midterm, ask me during that time. :)


If you missed this Q&A section, just ask questions in the Q&A page. Professor JAGGI and I will answer your questions in the Q&A page.


Please make good use of the online resources!

P.S. Professors and tutors are not the only guys can help, you can also ask your classmates. Last but not least, collaboration is very important when you are studying in the university!
