My school is sooo shit they wont let us take any1 to the formal and we ONLY HAVE LIKE 90 PPL in our grade ! My schools shitness is further justified as we still havent got our JERSEYS i mean yeah they came on the 6th of June but had to get sent back cause of all these errors i mean a few errors...

Definatly Permutations and Combinations but it becomes fun when u understand what u r doing and why.

I cant do i) because i forgot the solid formula lol but here is my answer for ii) y=lnx change this to x equals by this identity "log(a)y = x can be arranged to a^x=y" and then do DX/DY (yes dx/dy) and then sub in for limits 2 and 3. (your dy/dx will be e^x)

EXT1 does scale well but not like EXT2 which is like the 2nd highest slacing subjuct

I would say they are all the same as they are all linked

Hannah, dont worry about its only yr 11. BUT that doesnt mean u should take it easy. I would advise u to time 40min and write the essay within that time and hand it (unchanged) in. That way u will be more exposed to an exam situation and can reflect upon your mark. Justin

They cannot not let u do a subject just threaten to sue and u will be in the class (honestly)

because: when u equate the equation of the chord and parabola u will get a quadratic equation where the points of intersection or in this case the end points are the roots of that eqaution and when finding the x ordinate for the midpoint u must divide THE SUM of the x ordinates (i.e roots of...

MY school is the shitest school eva 1st. we cnt put names on our jerseys 2nd. we STILL havnt go em

lmao i just realised

kuzz it depends on ur personallity u c with me im the type of guy who can approach girls easily (so i like to think lol). U c 2day on the train i sat next to a random chick who was asleep then when she woke up i gave her a min then said "u know i had a bet with myself that u would have...

just by skimming through i suspect that that the end points of the chords are irational numbers and so when u use the midpoint formula and have to add them it will be hard. So by using the sum of the roots it is easy as it will give u a simple value of 4.

use the sub cos^2(ax) = 1-sin^2(ax) then make it into the form: ax^2 + bx + c=0 (with the sub that x=sinax) then find sinax with the formula: minus b plus or minus sq. root of b squared minus 4 times "a" times "c" over 2a. then do the 2k(pie) thing

its Is/Ip = np/ns

The suburb you live in: WESTMEAD Best / worst things about it: QUIET BUT NOT ISOLATED, CLOSE TO PARRA Is it a safe place? USED TO BE BUT CHANGING Is it multicultural? YES (VERY) Do the neighbours keep to themselves or interact a fair bit? INTERACT General age/career groups and...
