how to solve a set of equations for a ratio in terms of variables involved?
This is better explained with simple example. Suppose I have these 2 equations
a:='a';b:='b';x:='x';
eqs:=[3*a+4*b = 3*x, 5*a+7*b = 7*x];
What I want is to solve for (a/x) and (b/x) from the above, and not for "a" and "b".
Currently, I do th... | 4 | [

Limits
Find the trigonometric limit: lim (as x approaches infinity) (x-tan 2x)/sin 2x
We have $\frac{x - \tan 2x}{\sin 2x} = \frac{x}{\sin 2x} - \frac{1}{\cos 2x}$. Now consider the subsequences $x = 2\pi n + \frac\pi2$ and $x = 2\pi n + \pi + \frac\pi2$ to see that there is no limit.

roots via Newton-Raphson Method
According to this method, the cube root of a number a is obtained by starting with a guess x[1] of the cube root and using the formula
x[2] = (1/3)(2 x[1] + a/x[1]^2).
Thus, to find the cube root of 5, we take x[1] as 3/2. This guess is based on the reasoning that a value of 2 will be to... | 5 | [

Dynamics of dendritic cells
On 23.04 I heard a talk by Michel Nussenzweig from Rockefeller University. His subject was dendritic cells, a class of white blood cells. For the casual observer, such as myself, it might seem that
the class is homogeneous. It was emphasized by Nussenzweig that this is far from being the ca... | 4 | [

Explicit Definition of a Sequence
An arithmetic sequence is a sequence of numbers whose difference of any two consecutive terms is constant. This difference is called the common difference.
Example: 4,7,10,13,.....
The common difference is 3 and is found by subtracting any term from the one after it.
