Re: pdhpe funny acronyms when answering a Q we have Statement Explain Xample

for a textbook outcomes is good. i also use macquarie and dot point for study

thanks it helped a lot

got our marks back today - 63/65 i feel so good now.

the answer was like 0.5 ln (x^2-2x-1) - 0.5 ln (x^2 +1) + 0.5 x + C WTF!!!

ye the 4 units is 2U for ext.1 and 2U for ext. 2... that's why they hold the maths 2U and the maths 4U on the same day at the same time. btw most guys will tell you that u should spend equal time on both but 4U is so much work... :(

i know this looks like a simple Q but ∫ dx/(1+tanx) the answer has got logs and lots of crap in it... need help.

got a query on which substitution to use and how to do it in this question 2 ∫ dx/(x-1)(x^2-2)^0.5 1.5 btw the part with the x's is all the denominator. the only part in the numerator is the dx.

got some homework that i have no idea with. evaluate the following expressions lying between 0 and pi/2 simplify inverse tan x + inverse tan y and inverse tan x - inverse tan y

had ours on thursday.. hope to get it back this week. we got examined on harder 3U induction, conics (epic) and polys. the induction was so easy but it was a really long test 4-5 questions in 70 mins. most kids didnt finish. oh well, hope to get near full marks.

ye we got an assignment but it was just a teaching a movement skill report so i think our class should be getting at least 18/20 as a mean. im sure i got 20 but some ppl in our class are pretty lazy considering its pd.

just started integration... prove that 2 ∫ √(x(4-x)) dx = pi 0

got a question, never seen it b4. P and Q are the end points of a focal chord of the ellipse x^2/a^2 + y^2/b^2 = 1. if P and Q have parameters alpha and beta, show that e^-1 = (sin alpha - sin beta)/sin (alpha - beta).???? help pls.....

well i think patel is the best textbook around except for the extremeties that he has in the book - some questions are never asked in the hsc e.g. locus of ellipse. however coroneos' supplement (because it has extened sections) is also a fantastic book but the lack of curve sketching is a pain...

its just great how seinfeld got away with anything and everything. but my favourite episode has to be either "the implant","the contest", "the pool guy" or "the comeback"

got a question, P is a variable point on the hyperbola with focus S. PT is the tangent and P and ST is perpendicular to PT. Find the locus of T.

done complex polys complex and pretty close to finishing curve sketching

got 9 x 60 min periods 18 total for 4U for which half is actually 4U class

yes p1 x p2 = 4 its the same proof as prove that p1 x p2 = b^2... i just wanted to know about showing that the points of intersections between lines p1 and p2 and the tangent lie on the circle x^2 + y^2 = 9...

got a Q let the lengths of the perpendiculars from the foci of an ellipse 4x^2 + 9y^2 = 36 be P1 and P2. prove that P1xP2 = 4. Also prove that the points of contacts lie on the auxilary circle x^2 + y^2 = 9
