    What's 4U like?

    inverse trig and couting probability question

    domain of acos(x), or arccos(x) I think they're both valid.. arccos might be the fuller term: -1 <= x <= 1 (just punch ur calculator to check) the domain of asin(x) is the same range of acos(x) is 0 <= acos(x) <= pi... again, punch ur calculator.. find acos(1) and acos(-1) range of asin(x)...

    PaRaMeTriCs Q

    ok, the most common possible methods of doing parametrics are: 1. make the parameter the subject in one of the two given equations (x- and y- eqns) and substitute that to the other one If it can't be done easily, 2. square one of the given eqns or square both of them and look for some...

    Study for HSC

    revise then do probably about 3 more papers (3 from each course, ext1 and ext2) under timed condition and check it with the marking guideline to determine ur mark if u r satisfied, u can have a rest now :) but again, theres no harm in doing even more.

    unordered selection with repetition

    I think that's if it is ordered. Here's the types of situations I've gathered: 1. order is important 1.1. things (eg cards) are replaced as soon as each one is taken out: use n^k 1.2. things are not replaced: use nPk 2. order is important 2.1. things are replaced: ...

    unordered selection with repetition

    sorry.. the title of the thread should be "unordered selection with identical elements" But now I also have a question re unordered selection with repetition. Example: 5 cards are drawn from a standard pack of 52 cards. Each card is replaced as soon as it is picked up. In how many...

    What's 4U like?

    unordered selection with repetition

    Is this covered in the HSC course? I remembered thinking about it and couldnt find a working formula / method. example: 2 cards are chosen at random from a collection of 5 cards, labelled A, B, C, A, D. In how many way can they be chosen? That can be done fairly quickly without any...
