Re: HSC 2013 3U Marathon Thread
In the expansion of (1+3x+ax^2)^n, where n is a positive integer, the coefficient of x^2 is 0. Find, in terms of n, the value of the coefficient of x^3.
Haha, I'll admit the scaling is pretty good, and yeah I'm aiming to do medicine, but I actually find it really fun. Translating a passage is like solving a puzzle, although it can be really frustrating at times.
Nice. Are you guys starting revision on the texts (e.g. commentary)? We've finished Virgil, and almost finished Livy. How did you find the Latin study day (assuming you went)?
Hey, nice to know there's other people out there that do Latin! Currently, I'm just working on my Virgil and Livy translations and working through Liz's workbook (if your school has given it to you). How about you? How many people do Latin in your year. There's 6 people in my Latin class.

A harder 3u question (from Cambridge 3u):
A projectile is fired vertically upwards with speed V from the surface of the Earth. Assuming that acceleration = -kx^-2, prove that k = gR^2, where g is gravitational acceleration and R is the radius of the Earth. Thus, given...

The point P (which represents z = x +iy) moves in a straight line parallel to the imaginary axis. Prove that the point Q which represents z^2 moves in a certain parabola. Find the focus. Also describe the locus of Q when P moves on the...
