Best Subject: Maths

I believe that I can help in nearly anything about maths because I'm a fourth year mathematics student.

2. ## Re: Official BMGf Homework Tutor/Help Thread

Best subjects: Technology, Algebra, Language Arts/English, Writing, Proofreading.

Algebra maybe just the basics so far, but I can definitely help a fair bit with the other four.

3. ## Re: Official BMGf Homework Tutor/Help Thread

Best Subject: Maths and science

Well it looks like we need no more maths helpers but I'm currently taking a degree in maths so I thought I'd put it. :P
Preferably Physics of Biology but I also took Chemistry so I could help out there, just in how much detail I'm not sure

For 3xy-1-3x+y, you factorise it by grouping, where you group the terms into two separate groups, and then factorise accordingly.
So it will becomes something like this: 3xy-1-3x+y = 3xy-3x+y-1 = 3x(y-1)+1(y-1) =(3x+1)(y-1)

For (x^2-x-2)/(x-2), you need the factorise the numerator first. Then you will be able to cancel off the like terms.
So it will become something like this: (x^2-x-2)/(x-2) = (x+1)(x-2)/(x-2) = (x+1)

I'm not really sure how to explain the grouping part without confusing you, so I'd leave it to someone else to do it. :x

Also, can anyone explain the formation of meanders, slip off slopes and river cliffs for me? It'd be great if you used inner/outer banks instead of concave and convex banks for the formation of meander! (:

Were you aware about that you replied to a two years old post?

Nope. I just saw the date and assumed it was this this year. :x Sorry about it.

Best Subject: Has to be English. Not only do I take honors classes, but growing up in a Catholic elementary and middle school does has its advantages. From learning about verbs and adverbs to diagramming sentences, I'm your gal. I'm also pretty good at the composition of essays (intros, theses, bodies, and conclusions) and writing them. Not to mention reading comprehension and the many genres of novels and writing pieces.

I'm also first chair in my music class. I play the piccolo/flute so I can always help with reading music in the treble clef, flute fingerings, and also give help with those crazy runs. I would like to help with rhythm, but that would be a tad bit hard to explain on the internet. I'll try my best with that. Trip-a-let, trip-a-let...

Just let me know if you need help<3

Subjects: SAT prep, US History

I almost got a perfect score on my SAT's so if anyone needs some pointers to improve their scores I would be willing to help. I also received a 5 on the AP US History exam.

I'm not sure if this is still being done but here it goes

Subjects: Physics (Non Calc: Mechanics, Optics, E/M and Modern Physics, Calc based: Mechanics and maybe E/M)
Math (Pre-Algebra, Algebra 1+2, Geometry, Trigonometry, Single Variable Calculus 1+2 and Multivariable/Vector Calculus 1+2)

Hi there!
-----------------
Here are the exercises:
1)A vector is given by R=2i + j + 3k.
Find:
a) The magnitude of the x , y and z components
b) The magnitude of ''k''
c) The angles between R and the x, y and z axes.

2) Two vectors A and B have precisely equal magnitudes. For the magnitude of A+B to be TWO times longer than the magnitude of A-B , what must be the angle between them?

3) A firefighter in a distance "d" from a burning building directs a stream of water from a fire whose at angle "a" above the horizontal. If the initial speed of the stream is "v" at what height "h" does the water strike the building?
