That clock is so off putting if you're a year 12 student I reckon. But realistically, it goes so fast.

Hey guys, what 4U book/s should I borrow from the library/buy? (Maths):

- Cambridge
- Patel
- Terry Lee
- Coroneos
- Fitzpatrick

Thanks.

I know Carrot likes Coroneos for its questions and explanations and people say Terry Lee is good too

HEY can anyone please PM me the difference between DELTA>0 and DELTA=>0

 

[deswa1]

HEY can anyone please PM me the difference between DELTA>0 and DELTA=>0

When D=0- the two roots are the same. When D>0, the two roots are distinct

 

[RealiseNothing]

HEY can anyone please PM me the difference between DELTA>0 and DELTA=>0

DELTA>0 is when delta can only be greater than 0.

DELTA=>0 is when delta approaches 0 (I'm assuming that's an arrow, hence an approaching sign).

 

[HeroicPandas]

DELTA>0 is when delta can only be greater than 0.

DELTA=>0 is when delta approaches 0 (I'm assuming that's an arrow, hence an approaching sign).

and DELTA > 0 what is the difference between these 2................

WHAT DOES DISTINCT mean?

^ ALL REGARDING TO ROOTS

WHAT DOES DISTINCT mean?

^ ALL REGARDING TO ROOTS

Distinct means different.

 

[HeroicPandas]

Distinct means different.

OK so DELTA >0 is when i have distinct roots

when do i use this??

 

[asianese]

Real roots.

 

[HeroicPandas]

Real roots.

What do u mean real roots?
1. Do the roots have to be different? (How many?)
2. 2 equal 1 different?

EDIT: Well my guess is that real roots is when DELTA is positive
1. IF they say, real and distinct roots i use DELTA greater or equal to zero
2. IF they say, real roots i use DELTA greater or equal to 0?

 

[asianese]

Just look at the equation.



If the discriminant =0 then you only have 1 (real) root since the plus minus disappears.

If discriminant is positive then you have 2 real roots.

Yes i understand that BUT WHEN DO I USE DELTA GReater or equal to 0
and delta greater than 0

WAIT, post in year 12 chit chat

Hahaha

"Your results: test 1 = 7/20, test 2 = 13/20. Your final result is 50%, ranked 21st out of 28 students."

Lol shit that's a horrible ranking.

Meh, you're only in year 10. With consistent practice and hard work (which I'm sure you'll do.....), you can move up higher

Didn't you say there were King's students there as well though? King's isn't selective, is it?

Thats a great result, you should be proud.

Did you get the actual test paper with questions? I might give it a go if you have it - seriously though, I bet I'll full fail it because I'm not that far accelerated by my tutor. Also, improvements are good, so nice work I guess.
