Hi, funnytomato - been ages since! Greetings. Guys, if you are in his area, I'd highly recommend him. Bored is no longer the site I knew - so busy, so full of fun. Or is it just old dinosaur me?

A Message to Parents of Students Planning to do the IB Diploma Programme The IB Diploma is, in my view, a very rich, balanced and rigorous programme. In NSW, only a few hundred have the privilege to enrol in such a programme. You have to be enrolled in the score or so Independent schools...

Popular Australian view is: do what you like and enjoy. My view: do what would be beneficial to you, even if you may not like one or two of them.

The stoopid ATAR (UAI, TER ...) thing has distorted students' choice of subjects. If I were planning to do Medicine, I certainly would choose Chemistry, rather than subjects like French Continuers, Religion that have little direct bearing on Medicine. If your school is hopeless in Science...

I was just using the elementary non-calculus formula of Mechanics I learnt ages ago. S = ut + 0.5at^2 ==> 2.3 = 0 + 0.5 x a x 4.18^2 and f = 50 = ma

For a): is the mass about 190 kg??

Regardless of all the comments so far, I think you should not have dropped 3U, whether or not your teacher is "lazy". Falling back on bridging? I don't myself favour that route. Can you "undrop" your 3U?

C(t) = current at time t and C(0) = current at time t = 0 (initial current). When t=5, current has lost 40% of value so that C(5) = 0.6 C(0). Let t = T be the time at which current is reduced to 20% of C(0); i.e. C(T) = 0.2 C(0). C(t) = C(0) e^{-kt} \\ \\ \therefore C(5) = C(0)\times e^{-5k} =...

The area above the x-axis between y = 1 and y = 2 - 2/x can be split into 2 parts, A and B The latter curve cuts the x-axis at x=1, and the line y=1 at x=2. Rotating about the x-axis, A generates the volume of a cylinder (height 1, radius 1) = \pi $ $ u^3. B generates: \pi \int ^2 _1 1^2 - (2...

OK - I'll answer this soon.

If any of you need a one-on-one maths tutor, whether for the IB, the HSC, 1st Year Uni etc, please message me on 0490 - 780 347. I can now tutor at my place in Epping, or I can come to you, if you are within 15 km of my place.

You can learn from the master or you can learn from his apprentice.

If you are looking for a 1-on-1 maths tutor, please give me a call. I tutor at my place in Epping as well as at students' place if preferred.

Tutoring Yr 7 to Yr 12 (HSC) also. 1-on-1 or small groups at my place in Epping or at your place.

I was amazed to find that appropriate substitutions are provided in Ext 1. Why can't students be required to figure out the feasible substitutions themselves. In my HSC days, substitutions were very seldom provided. In the past, many questions required you to use the given substitutions; e.g...

I hate it when questions require me to use formal substitution. Without this restriction, I'd simply do it this way: \int _\frac {\pi}{4} ^\frac {\pi}{3} \frac {sec^2 x}{tan x} dx = \int ^* _ * \frac {1}{tan x} d tan x = \left[ ln |tan x| \right ]^* _* = ln( tan \frac {\pi}{3}) - ln (tan...

Where have you migrated from?

Since you have done so well in your 2U Maths(so-called Advanced!!), you should have no problem in doing well in you MX2 - unless you decide to smoke pot next year.

In your enviable situation, I can't imagine your not wanting to do 4U. What if, in doing MX2, you end up with an ATAR of 99.70 instead of 99.95, keeping your 2U results? I bet, in the end, you will do 4U.

Agree. Does not matter Enhanced or Original version; not much difference. Of course newer publications, like the new Fitzpatrick, with the benefit of more advanced typesetting, have much better layout and look more appealing.
