Anybody good in Algebra??? NEED HELP!

I kick ass in algebra.

So I signed up with a class online(stupid move) and thought I could teach myself this math class as it's algebra and I was good in algebra in HS some 8 years ago. Anyhow, I'm not getting it, and I don't want to fail, so if anyone is good in math, let me know, I have some parts I'd be willing to part with for some help.

Why don't you throw up your problem and lets see if any of us can help?

If you need a tutor, I charge by the letter/number typed.

Seriously though, there are some damn smart people on this board (maybe me included, but not really), so throw out your question and we'll try to point you in the right direction.

CChase86 · Feb 26, 2005

I'm decent at Algebra. If you post up some of the problems, no matter how hard it is, I'd be willing to bet there are people on this board who would figure it out (free of charge).

IronJim · Feb 26, 2005

im good in math, im in algebra 2. if you have any questions just ask

mack · Feb 26, 2005

You just need to remember this one thing are your set...

PEMDAS

LordOpie · Feb 26, 2005

I didn't truly learn algebra until Calc II.

Calculus is easy if you really understand algebra and trig. If you plan on taking calc, learn this stuff inside and out.

As for learning it, like the others said, just post questions. Some people here know math so thoroughly that they helped me even with Calc III, Diff Eq, etc.

Don;t you mean BEMDAS or BEDMAS???? whats the "P"....?

N8 v2.0 · Feb 26, 2005

I am good at Alzebra...

I took College Alg I, College Alg II and Trig all in a summer quarter. Made two A's and a B.

Like Loopie said, Calc is 10 calculus and 90% algebriac manipulation.

Akkkk I hate Cal :dead:

I'm still in Cal 1 :mumble:

the p is for parenthesis ... what the hell is the b for?

I'm taking differential equations as a freshman right now, its not too bad, but next semester: Complex Variables. That might be scary.

arboc! · Feb 26, 2005

whats involved in that class? is it a smart class or remedial class

-dustin · Feb 26, 2005

i had a couple friends who did DiffEq their freshman year. they were beyond what i consider smart. lacked a little common sense, though. i wonder if there's a trade-off.

arboc! · Feb 26, 2005

shoot me some questions if you want

I'm willing to part with one of the listed items for your assistance. I'm screwed with this class, I suck in math, it's been too long and my school is on the westcoast as I just moved to the eastcoast so I can't go in for tutoring. If your interested, let me know. Or if your interested in $250, that works too.

uhh, what's wrong with just asking questions here? We'll all help for free.

You could also go to the local community college, find the class, explain to the professor what's up and ask to sit in. I did that with Trig when I returned to college 10 years later. Forgot so much. Plus, the Trig teacher enjoyed having someone who was honestly interested that he chatted with me about some of the calc stuff on his own time.

Teachers love teaching. They sure don't do it for the money. So ask one?

If you really want a tutor and are willing to pay, find a student at said college to help you out.

yup, trade-off... typically. Partly from studying so much, partly from being different from all the "normal" students and being isolated.

Math is different in Canada. :stosh:

Ahh makes sense, all my teachers say b for "brackets" so same thing. I find BEMDAS is easier to remember. However, I know the stuff so well now it's not like I have to think...hmmmm bemdas which one goes first, addition??? :thumb:

mack · Feb 26, 2005

PEMDAS is far easier...

Please Excuse My Dear Aunt Sally

i didn't learn either of those in high school. what are y'all talking about?

It's just some little saying to help people learning algrebra the order of operations. So....brackets, exponents, multiplication or divison, addition or subtraction. :thumb:

I'll take understanding of complex concepts over common sense any day.

Not that the two have to be mutually exclusive.

We learned it out here as GEMDAS and the G is for Groupings.

diff eq means 'differential equations'

I consider diff eq just another calculus class. A differential equation is a basicaly a formula for a function in terms of it's derivative.
an example.

let y be a function. let y' be the derivative of the function.

now let
y = 2*y' + 3*(y')^2

" a function y equals 2 times it's derivative plus 3 times it's derivative squared"

find y. basically y is a function so y = f(t) or something. find the function f(t) that satisfies the above differential equation.

It's been a year since i took diff eq so i may have made some mistakes or something.

Oh, I have a headache just looking at that :confused:

It's just like walking into a Home Depot store.....deer in the headlights.......

Nate at RIT · Feb 27, 2005

Yeah DiffEq is essentially an extension of calc. What you have there is a homogenous nonlinear first order DE, but it's not in standard form.

I shoulda used a simpler example. I tried to solve that diff eq... i had to resort to using the computer. it was some complete insanity.

for instance...

y' = 2*y

find y

"the derivative of the function equals two times the function"

Well, this is easy to solve by inspection. let y = f(t) = K*e^(2t) (where K is an arbitrary nonzero constant). then df/dt = 2* f(t).

Pau11y · Feb 27, 2005

Ouu ouch! Only been thru Calc II (and III, but that has nothing to do w/ Diff Eq), and I can see the 3*(y')^2 part added to the headache.

Hey did you do calc III where you learn about greens theorem, stokes theorem, the divergence, and vector fields???? If so then you've dealt with diff eq's (probably). My calc III used diff eq's extensibly. However, we did not know that they were differential equations. For instance, solving for flows in a vector field is basically a system of differential equations...

[edit] my bad. that's calc 4 if you are using the quarters sytem. calc 3 if you have semesters. i think.

LordOpie · Feb 27, 2005

I came to understand why they say advanced math is a lot of educated guess work and intuition.

(always study!)

I hardly studied at all in my combo Diff Eq & Linear Algebra class and got a B. On the final examine is where I started to truly understand math. I finished the examine and just felt weird about two of the five problems. My intuition told me something was wrong, so I worked the problems backward and forward a couple of time until I found my mistake.

There is no spoon.
