Hey, anyone know what topic we start sketching graphs etc.?

Functions

I'm coping pretty good so far I think. We haven't done much extension stuff though so that'll probably change once we do.

That would be Functions.

Probably the worse topic yet....

Domain, range, limits, graphing inequations blah blah, blah blah....can't think of anymore LOL....

Some HORRIBLE stuff....

 

[xsjado]

I'm finding functions pretty straight forward.....

^ That's because our textbook is shit

As for now, I just remember Sin^2 + Cos^2 = 1. Then derive the other two from it. I am working to learn it by heart and practice it.

yah thats true ...

divide the entire thing by sin² x or cos² x to get the other 2 ...
you'll need to remember all 3 for the next years maths

*Worst.

Study more English. Kthx.

english is teh gayz sometimes

*sigh* should've done that in first place

I'm coping...I think. We've done Circle Geo and Polynomials, which I've found fairly easy, but some problems just get ridiculously hard. Tried to do some Ext 2 Circle Geo the other day, had no idea lol.

hey im just wondering, is it gona be hard to go quadratics & the parabola and circle geometry topic without an official maths teacher ? My teachers gona be on long serivce leave and I'm wondering how difficult it will be. I think circle geometry will be fine about what about the other ?

application of quadratics is difficult, but i dono what book you are using, if maths in focus, i am sure you'll be fine but the cambridge one is a bitch to do.
