Hi all,
I need to calculate the probability density function f\left( Y \right) of a function Y of two variables A and B with known individual probability density functions f\left( A \right) and f\left( B \right). What is the correct way to combine the PDF's?
Specifically, I have a...
Hi all,
I'm having a bit of trouble getting my head round approximations to a function in the limit of small and large values of the x parameter. The function is:
y = x\left\{ {\left[ {1 + \left( {{1 \over x}} \right)^2 } \right]^{{1 \over 2}} - 1} \right\}
The paper I'm reading says...
Hi all,
I have a set of equations that look very nice and symmetric, but the only way I'm able to find solutions to them is with pages and pages of algebra! Can any members with more of a mathematical flair than myself point me in the direction of a more direct and satisfactory method of...
Hi,
I'm familiar with the use of orbital elements to describe the motion of a satellite, and using those to calculate the state vector (position and velocity as a function of time) of the satellite.
I am wondering how it is possible to use this information to calculate when a satellite...
Hi all,
Can anyone show how I'd work out the analytical solution to an infinite series of this form:
\sum\limits_{n = 0}^\infty {\exp \left( { - An} \right)}
Thanks in advance,

Hi all,
Just looking for some opinions on how to approach reporting the variability in some data I have acquired. I know Rutherford is quoted as saying “if your experiment needs statistics, you ought to have done a better experiment”, but unfortunately in biophysics we’re always at the mercy...
Hi all,
I have a term in an equation that grows in an intuitive manner each time I increase the number of variables.
Basically, for an input vector of size n, this term is a sum of n terms, each of which is a product of n-1 components in the vector. Put simply, it is the sum of each...
