Math thread!

Anyways, I have a question: How do you find the greatest common factor for monomials such as:

4mn - 6mn(squared) :confused: :wtf:

Thanks!

Hey, what level/age are you sitting it at? Cos normally unless it's some trick complicated question I would go for the answer being mn(4-6mn). mn being the common factor.

Hope that's some help ;)

wouldnt it be 2mn? and the answer being 2mn(2-3mn)? *horrible flashbacks of highschool math* :lol: i havent done math in years, did stats two years ago but any time ive actually had to apply what i learned i just typed it into excel and the computer did it for me :lol: why did i have to spend 4 months learning to do it by hand when a computer does it for me???
 
Hooray! I suck at Math! It has been my worst subject since I got into school. I studied English and French in high school and we had absolutely no math classes. Now, I'm in college. And I've chosen to go on with one of my passions: geology. And now I take Math. The worst kind that there is on Earth. I failed my exams, I got there 2 marks (that's the equivalent of F) and I cannot understand why the teacher keeps poking me to go in front of 200 students and make a fool of myself in front of the blackboard. So, I see that you are a happy little bunch, with more Math skills that I will ever have in this life and the next one, and maybe you can give me a hint or two about what the hell Math wants from me, besides pure torture :D
partial differentiation & integration

This is what I'm doing these weeks. How? I stare at the blackboard and I try to listen to the teacher and I look like a moron. I bow down to people who can understand it. I really do.
 
:guffaw:Well, the teacher managed to explain but you guys helped as well. Thanks so much! :p

Sorry miss_blue, I can't help you with differentiation or integration without comming math suicide. And I'm supposed to take Honors next year... :lol:

I'm in Math 31 AP (also known here in Alberta as the torture that is Calculs AB) and next year I hope to attend University and get a physics degree. Ah, physics, how I love thee. *sigh* I really love that physics has obvious and real applications, and that I really understand it. Calculus, pshaw, there I'm lost. First I had to wrap my head around "first of all 'x' doesn't equal 'a' it approaches 'a'. and we're not looking for the value of 'x' we're looking for the limit as 'x' approaches this value." I did eventually get it and when we did related rates I actually understood everything! (mostly because it's just modified physics with no real point)
Now we're doing differentiation and itergral coefficients and I'm only starting to understand it. I do undertand the anti-derivitive, which makes my math teacher happy. I think she's tired of looking at me and seeing me stare back with a blank look. I get it! But not like Dustin the math wizard over there. *headdesk*
One thing I do get, slope fields. We started those today, and after I stared at her blankly for five minutes waiting for her to explain what the hell they were, and after I figured out how to guess what the slope looked like, I had it down!
My math life, see my signature below. VV and my location <<
 
x^2 becomes 2x and the other way 2x = x^2 differentiation & integration - muwahahahaha. Can anyone remember the need for it in real life? I'm sure there is one but I blanked it out. :lol:

gotta love calculus! except when it gets ridiculous like having to remember 22 different integrals for an exam!
don't you think its great that when you differentiate e^x its exactly the same as integrating e^x which is just e^x anyway!

i'm in the process of deciding my firm choice of uni for to study maths so i was wondering if i could ask some people to check out the course an give me your opinions???

this is for the uni of hertfordshire
http://perseus.herts.ac.uk/courses/pam/mathematics-bsc.cfm
and this ones for nottingham trent
http://www.ntu.ac.uk/prospective_st...hematics/5C85CC9F-8B49-49F6-96A1-AF3FABB7375C

thanks in advance:)
 
Hertfordshire sounds good, guess it just depends on what you're wanting to do with yourself afterwards. My uni ran a financial degree which led to careers in actuary (think that's how it is spelled) and other complicatedness. Lot's of people from my course ended up taking statistical positions in NHS and such places, myself, I'm about to enter a post grad in Primary Teaching (torn between :scream: and woohoo!) :lol:

Maths is a good base degree in the sense you can have said tormenting career in statistics or teaching or really as a basis for any decent job. It's always adaptable and thankfully the market isn't crammed with us. Unlike psychology, where - yes it's a good degree but you must go and specialise.
 
Thanks Little Peaches!
I think i will possibly go the teaching route also except at secondary level. I really enjoy statistics and I could always do a postgrad? But i'll most definately be heading towards teaching.
Is anyone else considering this?

Yes. That's great, and so easy to remember. Doing Intergration by substitution is the easiest thing I've done since related rates. I actually get this, except remembering the trig derivitives.
 
yea the trig derivitives are a right pain!
So i went to see Nott trent the other week and i loved it so 've put it down as my number one choice! I'm really excited now and the lecturer told me that as long as I don't fail all my courses and do horribly in maths i'm virtually guaranteed a place!!!!!

:cool: My parents both went to Nottingham Trent, back in the late 60's/early 70's when it was the teaching college. That's where they met, doing their respective teaching qualifications.

Sorry, I can't really add anything else to a thread about Maths. I'm forever grateful for my grade C in GCSE, and anything more is just beyond me. I don't feel that I need to know Maths though as my husband has a degree in it, so he does the Maths for both of us. :lol:
 
Hey Grssom89 - yeah, do the degree in something you enjoy and just go for the post grad. Not to mention the amount of big firms that will hire you with a degree in Stats (electrical/gas companies, NHS, there's another biggie but I can't remember it right now :lol:)
 
Thanks for all your support and guidance everyone now the only obstacle to overcome is getting those grades!!
