Ok Good... Thanks. :)

Hello All.... If I had to solve the following equation: x^6 - 7x^3 - 8 = 0 Would we let a (or whatever pronumeral) = x^3 for a start? Thanks in advance... :)

Yeah true... :D

Which ATAR Calculator do you use? I've used a couple and they give different results.

I eat too much!! My list would be so long!

Mmmmm, is delicious... Feeling a bit ill now!

Haha!! I've eaten so much homemade chocolate cake (+ chocolate icing!). :D

Yeah ok, I will. :D Very true... Shall do! :)

Right thanks... :D so a) x = -0.236, 4.326 then y = 1 b) x = -2, 4/3 then y = -8

Hello All. :) Q. Sketch the graph of each parabola showing any intercepts, the axis of symmetry and vertex. a) y = 1 + 4x - x^2 b) y = 3x^2 + 2x - 8 I'm not sure about how to work out the x intercepts.... Could someone please help me? Thanks in advance. :)

Thanks heaps... :D

Is the new PRELIM syllabus very different to the last syllabus?? :D

Your correct... (no worries!!)... Can you think of any off the top of your head? I was thinking Darrel Lea for Post Maturity...

Is this right?

So for b) am I correct in saying the Gradient of the Normal at x = 2p, -1??

How about this question ... I need help with b and c. Q. a) Show that the point P (2p, p^2) lies on the parabola x^2 = 4y. b) Find the equation of the normal to the parabola at P. c) Show that p^2 + 1 = 0 if the normal passes through the focus of the parabola (p cannot = 0). Thanks. :)

Thanks. You are correct. :)

Can anyone give me an example??? :)

Can someone please help? :)

Hello All... :D I've got a few questions... 1. i)Find the coordinates of the focus and ii)the equation of the directrix of y^2 + 6y + 40x + 29 = 0 2. Only part b I need help with. a) Sketch y = x^2 + 2x - 8, showing intercepts and the minimum point b) Find the coordinates of...
