Oh.... Finally, this is weekend! Yeah I am so glad for passing such a though week after practicum. I start exploding haha. I need rest and a little refreshing moment. Anyway but that's not for last night. I fel very stess and burdened because I got so many homeworks and also going to Exam!! I just played and enjoy the violin to supress the stress. Even though Herbetd, Edberg, Robert and Jeko (my room mates) teased me and suggested me to finish my concert, I'd not pay attention to them :P, I enjoyed my self.
Tis just remind me to the concept of self efficacy, maybe because I felt that the assignment given is a bit hard so my natural being wanna to flee or escape. Therefore it is also connected to the concept about escapism in my article under title of "Substitute".
OK, now depart from psycho talk and then to my reflection on today's class. It've been awesome by the way, because I felt really life in the classrom. The explanation about determinant, adjoint and inverse of matrices made me sense.
And I remembered one thing about the determinant can be solved with several ways; general way, Row operation, etc.
Or by using cofactor relation which I can get from (-1)^i+j [ad-bc]. The adjoint is [(Cofactors)]t.
And then A-1 is 1/det A [Adjoint].
After the lecture, I attended the exam. I was very enthusiastic to be one table with Mella, Ko Ko Petrias, Saras, n friends. And that's not as hard as I tought before, hm and thank you for Mr. Dylmoon!
OK, Bravo Mathematics......
I always love math stuffs
