# 8.2: Factoring Polynomials
You should be familiar with the quadratic formula, which allows us to factor any polynomial of degree two, into linear factors. Specifically, it tells us that the roots of $$ax^2 + bx + c$$ are
$\dfrac{-b ± \sqrt{b^2 -4ac}}{2a}$
Notice that this does not tell us immediately how to fact... | {} |

# What is a gravity gradient?
The statement: 'For most of that day, Mir remained in a "gravity gradient," (sic) which basically means that the most massive part of Mir naturally pointed toward Earth.' is in https://history.nasa.gov/SP-4225/nasa4/nasa4.htm .
I don't understand this at all. Why would the most massive p... | {} |
### METHOD OF MOMENTS:
The R implementation can be found in the gmm package.
Once decided that a sample comes from a normal distribution, the parameters $$\mu$$ and $$\sigma$$ can be estimated by either the method of moments or the generalized method of moments.
In the method of moments the two first moments of the ... | {} |
# Evolution of spectral and transport quantities with doping in the SU(2) theory of cuprates
Abstract : Recent transport experiments in the cuprate superconductors linked the opening of the pseudogap to a change in electronic dispersion [S. Badoux et al., Nature 531, 210 (2015)]. Transport measurements showed that the... | {} |
# Asymptotic integral expansion of $\int_0^{\infty} t^{3/4}e^{-x(t^2+2t^4)}dt$ for $x \to \infty$
I'm still having a little trouble applying Laplace's method to find the leading asymptotic behavior of an integral. Could someone help me understand this? How about with an example, like:

In LTE/NR telecommunications, OFDM is used as the method to encoding digital... | {} |
# Why do we have to take torque due to pseudo force for an accelerating axis?
For e.g.
Here, A,B are strings. A was cut. The rod is of length l. Acceleration of center of mass = a and angular acceleration of the rod is alpha.
Now if I want to find the net torque about the point of intersection of B and the rod(which... | {} |
