What are you learning in your math/algebra/whatever class?

We're doing parabolas at the moment. Fun times...actually they are kinda fun.

we just finishd that...fun????? lol speak for yourself ;)

rite now we're doing ummm...*thinks* o yea, solvin linear regressions algebraically and um..sum other stuff too *shrugs* i hate math sooooooooooooooooooooooooooooo much

Umm... we just finished the quadratic formula... eek...:eek: I had a test on it though yesterday -- got a 98, so it wasn't that bad!

(Or maybe it's just because my algebra teacher makes really easy tests... either one)

haha i just finished that one 2!!! that was all last chapter! i got a um......90 on the test :-D

well...here is what we just did....my math program is different and its not offered at all schools...

In the process, students are introduced to the normal distribution and the standard deviation as tools for determining whether a change in one variable really does affect another. They make and refine conjectures, analyze data collected from experiments, and use graphing calculators to learn about quadratic equations and to explore curve fitting. Finally, after deriving a theoretical answer to the problem, students actually build a 30-foot pendulum to test their theory.



heres what we just started

This unit opens with the question "How can you predict the length of a shadow?" Students experiment with flashlights to isolate the important variables and try to predict the length of the shadow in terms of one of those variables. In order to understand shadows and the data they have found, students need to learn some geometry.

Students work with a variety of concrete objects to come to an understanding of similar polygons, especially similar triangles. They then return to the problem of the shadow, applying their knowledge of similar triangles and using informal methods for solving proportions to develop a general formula.

In the last part of the unit, students learn about the three primary trigonometric functions—sine, cosine, and tangent—as they are defined for acute angles, and apply these functions to problems of finding heights and distances.



(i found it from a site bout it...hehe)

Hmm.. in geometry we're doing a lot of algebra review, like the equations of lines and finding slopes and finding the magnitude of a vector and all that stuff. We did most of it in algebra last year, though. After this we'll do constructions and loci, and then it's end of year exams (eek!).

LOL i dun really know cuz i barely pay attention but we just had a test about geometry and i hate geometry

Eh...Don't get me started about my Algebra II class............

I haven't had Math for a year and a half. At my school we only have to have 3 math credits to graduate.

Rational expressions. We've had to find the domain, simply, add, subtract, multipy, and divide them... they're hard. And Amy...... parabolas arent fun.. lol

lets all sing the quadratic formula song!!

*singing to the music of the Notre Dame fight song*

x equals the opposite of b!

plus or minus square root of..

b squared minus 4 a c

all over 2 times a!

They sing that to us at my school... haha its funny and it made it really easy to remember.

We're learning derivatives.

In Geometry we are currently learning how to determine images and preimages and what they preserve, how you determine they are equal, and what not. I don't know for sure, but I have two weeks until semester exams and I'll have to dig back to the deepest cavern of my brain and attempt to recall everything my teacher attempted to teach me over these past 18-20 weeks. Wow, that outta be a piece of cake:rolleyes:

well yesterday we learned "invisible numbers" and today we learned to graph parabola's using the formalue b squared - 4ac
and finding the vertix and graphing it and all...

HEY!! That's to the tune of our school song!!

*sings*
Stand up Troy and sing loyalty!
Raise up your voices, shout victory!
Sound the Trojan cheers on high!
Shake down the thuder from the sky!!

-ahem-

I'm done.

I know the formula without singing the song. And yes, Jeff, parabolas are fun. :p

Are you in my class?:) I'm in Algebra II. I wouldn't mind math if I would ever have a teacher who taught it!!! There's only 5 people out of 20 some kids who are passing my class including me! My teacher is all the time talking about himself & everything he knows & talks about his religion. He also talks about drugs & how we're all on them & that's NOT true! NOW he's finally starting to teach some stuff when school's alomost out!!!!! It upsets me a lot...In class we're trying to learn polynomials & other problems. Well, I can't wait til school's out cause I don't have to have anymore math credits!!! WHOOO HOOOOO :wave:

AAAAAHAHAHAHAHA!! !FUUUUUUUUN TIMES!!!!!!! Step 1.) Up or down? Step 2.) Zero points. Step 3.) find X by taking the average of the 2 zero points. Step 4.) Substitue X in the original equation to get the vertex. Step 5.) Find more ordered pairs. Step 6.) Plot the points!




HOW FUN!!!

OMG You are my Cosmic Twin! First, our towns are boring, then we have block schedules, now this. My teacher is a great person but a horrible teacher. He just talks about how if we drillfor Oil in Alaska it won't be enough if we cut away form Saudi Arabia and always always always talks about the National Debt and how it was better under Clinton because he actually paid it off and how the Catholic Church was so off on the birth of Jesus beacuse he says he was born not in December, that it's not even funny. Out of school he's a great guy, but as a teacher, he's horrible. And NOW I finally understand some material and I didn't know anything since the begining of the semester. The whole class was liek that. This is the first time I feel like I Understand! So does the rest of the class. What are you in high-school? I'm a junior. :D

OMG,I can't believe it!!!!! My teacher was talking about the same exact oil thing just last week! Someone was talking about Afganistan(sp) & he started talking about oil in Alaska & all that! He's always talking about the nation & money & he was talking about Clinton too. That's pretty weird..Maybe it's the same person lol! I'm also a junior in high school. Wow, we do have a lot of similarties! Well, it's late & I'm gonna go. Talk to everyone later:wave:

how to make % into fractions. Ha.
