anhydrouscoppersulphate SG mostly four la anyway i got qns for summation and series that have rrly large no. or very small no.
DriftingGuy SG Got! The paper asked me to do 8x8 simulataneous equations... but hinted that this can be downsized to 4x4 once you figured out the trick
ndmmxiaomayi SG Wah lao.... students supposed to do research what... I throw you the VB codes, you compile, then make it into calculator can?
ndmmxiaomayi SG A Maths got teach. Can't remember it though. Use matrix to solve. But will die doing it. 2x2 already take up one page of foolscap paper.
