btw 我17都用到幾條program,
嗰啲program係幫我計快啲
btw 有個補習老師d program好勁, 一個program有曬所有功能
(e.g. 圓形program
find eq. of straight line from a given point(on circle),
find eq. of straight line from a given point( outside circle),
find eq. of straight line from a given y intercept,
find eq. of straight line from a given slope,
3point
general from <-> center + radius
)
直接秒咗2016最尾嗰題
二元二次:
佢會出埋步驟要求嗰啲step, delta, etc
佢d program唔知點解係網上流出咗, 而家上網搵唔番
嗰陣時都入咗呢兩條入去, 雖然圓形program最後無用到
