      The solutions will be posted on this page each morning. You can also ask further questions on the specific issues that may require clarification.

    it looks like it is either pne gets full mark (2) or nothing in each question. As I noticed there was not mark attached to solutions that were correct but not clearly stated.

    Good day sir,
    To start with I appreciate your charismatic, lively and hearty style of lecture. I always look forward to your class.

    Sir, I need you to throw more light on this confusion I have concerning a certain step in one of the solutions you gave us, precisely on vector assignment. In home work 1, number 3 there is an evaluation like this:

    (jrCos[ϕ]-irSin[ϕ] ) x k= -irCos[ϕ]-jrSin[ϕ]

    However, with my elementary knowledge of use of matrices and also the vector product I learnt in continuum I got this:

    (jrCos[ϕ]-irSin[ϕ] ) x k= irCos[ϕ]+jrSin[ϕ]

    Please advice.

    Best Regards.

      You are correct; I am wrong! We will settle it and I will update my notes. Thanks for drawing attention to the fact that I have unwittingly multiplied the result by -1.
