Nantuko_HuskI knew this had a problem , just i wanted someone to find it. I am have been preety sure most people would have got confused in the square difference
where 4² - 2 * 4 * (9/2) + (9/2)² is [4 - (9/2)]²
but it is simple
(a+b)² = a² + b² + 2ab
so ( 4 - 9/2 )² according to the above formula is
4² + (9/2)² + 2 * 4 + 9/2
arent those same. some just didnt want to understand it and kept saying that i was wrong there,
Yes that is almost right... Its's probably just a typo but I'll change it anyway.
DaelinWe don't have your education system. Grades 1-4: Primary School Grades 5-8: Gymnasium Grades 9-12: Highschool
You start at the age of 7 so I should be in 9th grade, but I started school at 6 so I am in 10th grade. So, let's see:
In 9th grade we learnt trigonometry, functions (revision grade 1 and learnt grade 2), mathematical induction, vectors, progressions, and some other stuff I can't remember.
Grade 10 we made by now functions (injective, surjective, bijective), logarithms, radicals (n grade, since grade 2 is square root and we made it in 7th grade), and I dunno what's going to come. I saw some specific functions (logarithimical and other stuff) plus we will make probabilities.
As for geometry part, we started learning complex numbers, and we will begin with analitical geometry as well in the second semester. There are probably other stuff but I didn't look in the book to see. I don't care. Math is one of the subjects at which I suck.
Derivates, limits and stuff like that... I think that's 11th grade math. Yeah, 11th grade will surely suck.
Oh, and Nantuko, you're older than me. I wouldn't be surprised if you started learning limits.

crap... I want to learn that too ;] I am moving to Romania w00000t
I am in kinda like 9th grade (from 6 years old) and we are learning angles in polygons (calculating), algebraic expressions... we should have in last month of school trygonometric functions (Sin and Cos)...
So, let's see:
