Choice of M1&M2 唔知點揀 (20分)

今年中三既我唔知揀M1定M2好.

01. 我數學都OK 中上

02. 我想做機師

03. 我會讀Physics+BAFS+Econ

04. 我唔係好明M1同M2既分別 好似冇咩分別咁

    M1 - statistics + calculus

    M2 - algebra + calculus

    M1: more about calculation, such as probability, normal distribution, intervals....

    M2: more about graphs, equations, trigo.....

    If you choose M1, it would help BAFS and Econ

    If you choose M2, it would help Physics

    They would not have any effects on your future job as a pilot

    I suggest you to go through some syllabus of both M1 and M2 first before you make your choice.

    You may go though the syllabus in the website of edu bur : (P.34)

    睇你讀大學/HD想讀咩科喇,

    M1係統計學與代數

    M2係代數同微積分,

    簡單咁講解下咩係微積分,

    微積分,顧名思義,

    即係分有微分(differentiation)同積分(integration )兩部分,

    differentiation 係教你搵方程式(equation)既

    1.頂點

    (即係最高/最低果點,e.g.一個人最多可以搵到幾多錢呢?, 就係睇條式既maximum point)

    2. 斜率/切線(slope/ tangent)

    (slope中三應該有教,tangent係slope既方程,簡單黎講當x=1,slope係幾多,

    而when x=2, slope又係幾多呢,依家中三教既直線,佢既slope係不變既,e.g.tangent(dy/dx)=3,而在其他曲線既方程,dy/dx=3x,所以在唔同點,有唔同既slope )

    例如在普通數學,

    求一載滿水.面積為3cm^2既圓柱體,

    當每秒漏出 1cm^3水時,高度會下降多少?

    M1/M2就要搵:

    求一載滿水,高度為10cm,底面積為3cm^2既漏斗(圓錐)

    當每秒漏出水1cm^3水時, 在某高度(e.g. 3cm)時,高度會下降多少

    如果用物理方面黎講,我地可以用differentiation黎搵佢既速率,加速度,

    積分就可以用黎搵

    1.面積(area)

    2.體積(volume),

    在M1同M2所教既分別就係, M1會學少 sin, cos, tan 既微積分,

    而呢D部分,物理係會用到既(當然中學既物理課程係唔會計微積分)

    在M2代數方面,

    代數係咩? 最簡單既例子: x +3=5

    而M2入邊教既就係:

    sin(a+b)=sin(a)cos(b)+cos(a)sin(b)

    sin(2a)=2sin(a)cos(b)

    除左平時數學用開既方程,

    佢會教你更多唔同既計算方法,工具,

    例如 matrix,同vector

    matrix最簡單既用法,

    就係解three-variable linear equation(三元一次方程)

    e.g.

    x+y+z=10

    3x+6y+z=19

    2x+y+z=11

    用matrix就會表示為

    (1 1 1)(x) (10)

    (3 6 1)(y) = (19)

    (2 1 1)(z) (11)

    而vector,

    最簡單既形容方式,就係講畢氏定理既走棧位

    有冇諗過,如果要有兩條連埋既直線,

    當要搵佢頭同尾既距離,係要點搵呢?

    畢氏定理,係 a^2+b^2=c^2既?

    你諗下,如果在表達上,將條直線既「a」同「b」分開寫,

    咁加去上黎咪會好方面?

    即係如果a=3,b=4,c=5,

    平時我地會寫佢長度係5,

    而vector就寫成 3i+4j

    vector在物理好多方面都好有用,例如在力,交流電,etc.

    大概講住咁多先,

    最後,最重要既公開試方面:

    我有朋友數學2...但M1 5**, 當然有好多數學2/3既人都拿到 3/4

    而M2,大多數人都係數學5**,M2係5*, maaths 5=> M2 4.......

    可以講既係M1算係「數學中既文科」,

    著重死操死溫就可以考到高分(當然係鬥小心,)

    而M2,

    就著重 活學活用,數學有一定程度,

    要理解 用法同意義,原因,

    先會拿到高分,

    但當然,比起鬥小心,一般數學人會相對合適讀M2

    簡單黎講 M1易過M2, M2學既多過M1,

    上到大學/大專,讀數理相關既計數科目:

    學過M1既會比冇學過既有優勢,

    學過M2既會屈冇學過既機,會比M1有優勢。

    2014-07-04 06:54:59 補充:

    不過,

    最重要既係你有冇能力讀M2,

    中上唔知你點定義喇

    但我以前中學讀M2既,數學上全部人都係9X/100分,

    出到黎只有5,6個拿5**/5*,有6,7個係得3, 仲有3個係drop左

    反觀M1....有幾個數學考試唔合格(校內試)既女仔都可以拿到高分......(主因佢地計數好小心)

    我覺得M1同M2對飛機師冇咩用,可能M2(多CALCULUS)有少少用都唔定,

    但前題你要入到大學或者有好成績先得,

    咁我會覺得你先睇下M1易讀D定M2易讀D,

    令到你可以係DSE考到好成績,

    提升上大學既機會,

    再係大學先學多D關於飛機既知道eg.mech
