I had my first paper in the afternoon for my repeated module, Engineering Maths 2. The questions are relatively easy, except that I totally forgot the method of doing. It just simply didn't cross my mind. Made careless mistakes here and there. Why are there so many god-damn formulas and properties? I AM not exaggerating but there are at least 150 fucking formulas, properties and characteristics that I ought to remember and know. Why the fuck is it not an open book? Why must i remember all the fucking Ifs? (A) Elementary properties of determinants:
1. If every element of a row (or column)
of A is zero, then det(A) = 0.
2. det(A) = det (AT).
3. If all the elements in any row (or
column) of A are multiplied by a
scalar α, then the determinant is
αdet(A).
4. If A is nxn, det(αA) = αndet(A).
5. If B is the matrix obtained from A by
interchanging any two of its rows (or
columns), then det(B) = -det(A).
6. If two rows (or columns) of A are
identical, then det(A) = 0
7. If B is obtained from A by adding to
the i-th row (or column) a scalar
multiple of j-th row (or column) (j ≠ i),
then B = A.
Rong and Wanqing saw Liting under panic attack last night. Panic attack is forecasted to be full blown from this weekend.
I have four fucking papers next week. There's nothing much that I can do other than study more and perhaps pray. I simply hate the feeling of stepping out of the hall, wondering if i would manage to scrape through (it's not even about passing with a decent grade or doing well). Anyone understands? FUCK the exams!
