Does anyone know a way to typeset a long division in LaTeX? I'm particularly interested in: \frac{1}{\cos x} = \frac{1}{1-\frac{x^2}{2!}+\frac{x^4}{4!}-\cdots} Thanks

Hey, A while ago i hear about finding the division number theory [Tell how a number can be divied be another unmber as a general formula]. And i am wondering if there is a theory "desicovered" the pattern of the prime numbers. Or at least a fixed pattern for predicting some of the prime numbers...

HI please can someone help me with this quick question on division : If I have to do 3 divided by 4 ____ 4 |3 4 doesn't go into 3 so I put a zero on top . When it gets to 4 into 2(from 30-4x7), it doesn't go, so why don't I put a zero on top but instead put a zero beside the...

From school, we've had addition, "subtraction" of vectors and then scalar multiplication, dot & cross products. I have never come across dividing a vector by another. Is there such an operation? Eagerly awaiting enlightening replies, Nanveeth

could anybody be kind to explain what is cell division to me please? i only know is that its chromotins duplicated.

Hi all, I'm working on this problem in my Geometry class, and am having a bit of trouble coming to a conclusion. The problem as given is (I've attached the figure to this thread): From this information, I have deduced that triangle DCB is right isosceles, with DC = CB. Also, since <DBC...

[FONT=Times New Roman] For a long time now I have pondered over our universal acceptance of empirical science, our methods, our successes...and its drawbacks. At the same time, I see a whole lot of unanswered questions, some of them "factual", but because they cannot be the subject of grant or...

Division by ZERO! Hey guys! Was just pondering... ALL my mathematical subject lecturers go on and on and on about trying to avoid division by zero. Fine - after all, it makes logical nonsense to divide by zero but my pondering thoughts led me somewhere... Is it possible to do some...

Hi, I'm currently reading "Calculus Made Easy" and ran into a road block. I'm reading this in my spare time so it's not school work or anything (I know some forums have policies about this is why I mention). The answer is there. I just want to know how to go about doing this problem. It...

I was learning polynomial division, and I can do most problems, except this one which is bothering me. : 3x^2 + 2x + 7 --------------- (1+i)x - 2 How would I divide something like that? Nothing is working. Thanks.

Help! :confused: Here I am busy doing some Laplace Transforms for my Maths 2 paper on Monday when suddenly to my surprise, an apparent "mistake" appears! GASP! :eek: It's got to do with the Heaviside "cover up" method. To work out a problem, you need to multiply the opposing side by...

Hi all, Before I ask a Q about blood cancers, can I just check - is it right that cell division of blood cells takes place only in the bone marrow (and not in the bloodstream or anywhere else)? Thanx Charles

If I have to find the quotient q and the remainder r and: a = -5286 b = 19 How do I go about writing down the steps for this algorithm? I know what the answer will be, but I need to be able to use the division algorithm to prove my answer. Like I know if: b > 0 and a < 0 (which in this...

Just seen an interesting documentary about the breakthrough in Cancer treatments. The programme gives a brief discription on cell division and how doctors think the way forward for treatment is changing due to the Understanding of Genetic (genome) discovery. Anyway I was fascinated by the film...

The number 2 What if the number 2 is the origin of whole numbers? (Instead of 0) The criteria for a whole number would contain that a whole number would primarily need to be wholly divisble by 2. does 2/2 = 2 as there are 2 combinations of the halves of 2 I think this can be...

What does it mean to multiply two physical quantities? Ie: For electrical potential energy the equation is Ee=kq1q2/r Where k=Coulombs constant, q1 and q2 are charges in Couloumbs and r is the distance between the charges What does it mean to multiply q1 and q2?

I am wondering about the differences between plant vs animal cell division, mainly about cytokinesis. Is the following a true generalization? Plant daughter cells separate by forming membrane vesicles that line up in the center of the cell and fuse to form new plasma membranes. Animal...

Multiplication is defined as repeated addition. 3x5 = 5+5+5 How do we define 10/2?
