We will need to arrange one extra class in the next two weeks in order to complete the section. A class test is for the week of April 4.

    Thank you Sir.

    Thanks again for your patience with us, we are looking forward to a better performance going forward owned to the learnings from our past experience.

    For the extra class, I will suggest a Saturday, and possibly moving the whole class to Saturday going forward, In my opinion, I think it will give us the elegance of working through the concepts without any interruption from other lectures as experienced during the weekdays.

    Page 34: I understand that Tu is the difference between unit (n.u)n however, please clarify how (n.u)n represents the projection.

    Tu = 1u – (n.u)n = u – (n.u)n

    • oafak says:

      Elementary: n.u= |n| x |u| cos theta. Since n is a unit vector, its magnitude is one. Hence n.u is simply |u| cos theta. That is the projection of u on n. When you multiply this scalar by the unit vector n, it becomes the vector projection! What more explanation do you want? This is SS3 stuff!

  4. Aristobulus T says:

    The concept on slides 53 and 43 (tensor components) seems to tally . However, I need the clarification why the superscript beta on the penultimate line transformed to alpha on the tensor S and the index j on the last metric tensor g on final line? Please clarify.

    Good Afternoon Prof,
    I want to use this medium to apologize for lack of activity on this platform, from my own end, I personally work with the reference texts for clarity on any concept that is not so clear in the note, but in other not to excuse myself, I need to state that we’re working together to ensure we all get along well together with the course through an organized tutorial class and a whatsapp group. Regarding the last test, the week was a very busy one for most of us as we have 3 tests scheduled for that week and we’re trying to strike a balance, furthermore, due to the fact that we were expecting a computer based test which offers a wider coverage of the scope of the topics covered.
    We will like to apologize and ask for your availability for tomorrow’s class sir while we look forward to a better performance from the strategies we’ve adopted to get it right.
