    Ellipse and Hyperbola

    Can anyone teach me about ellipse and hyperbola?
    Especially,
    \frac{x^2}{a^2}+\frac{y^2}{b^2}=1

    \frac{x^2}{a^2}-\frac{y^2}{b^2}=1
    \frac{y^2}{a^2}-\frac{x^2}{b^2}=1

    The grade range is from 1 to 9.
    1 is the best.
    Grade 1 and 2 are A, called 1A and 2A, 1A is better than 2A.
    Grade 3 and 4 are B, called 3B and 4B, 3B is better than 4B.
    ...
    The ascending grade sequence is 9G,8E,7D,6C,5C,4B,3B,2A,1A.

    no. we study a lot more. but towards the end of high school we are told to pick subjects that we want to specialize in. Three subjects are mandatory, including math and english, but for the others, you can pretty much do want you want. so a science person would choose science courses and so on. in all, you must do at least 8 subjects

    I see. When we Form 6, we need take General Paper(in malay), Mathematic, MUET and 2 more subjects. Science students should take Chemisrty and either Physics or Biology. Totally are 5 subjects.
