$\Large \int\limits_\frac{-\pi}{4}^\frac{\pi}{4}\frac{dx}{1+\cos2x}$ is equal to $(A)\;1\quad(B)\;2\quad(C)\;3\quad(D)\;4$
Toolbox:
• If $f(-x)=-f(x)$,then $f(x)$ is an odd function.
• If $f(-x)=f(x)$,then $f(x)$ is an even function.
• $1+\cos 2x=2\cos^2x$

# Commutation of the partial derivatives on scalar in xAct
I do not know how to automatically commute partial derivatives on a scalar and simplify it. For example, if I have: $$\partial_a \partial_b \partial_c f- \partial_c \partial_a \partial_b f$$ where $$f$$ is a scalar function, the ToCanonical and Simplification ... | {} |
The I key on the keyboard of my 12 year old Dell laptop has become very difficult to use (need to press VERY HARD to produce an I), so I am considering upgrading to my 10 year old Macbook Pro. I had installed dual boot Ubuntu 14.04 on it several years ago, so I fired that up, then ran update-manager, clicked to upgrade... | {} |

# What are the absolute extrema of f(x)= xsqrt(4-x^2) -x in [-1,2]?
Feb 24, 2017
Relative max. at x = 1/2 sqrt(1/2(15-sqrt(33))
Relative min. at right endpoint: $\left(2 , - 2\right)$
#### Explanation:
Rewrite equation:
$f \left(x\right) = x \sqrt{4 - {x}^{2}} - x = x {\left(4 - {x}^{2}\right)}^{\frac{1}{2}} - x$

# Chemistry - Do isotopic groups cause optical activity?
## Solution 1:
From a 2007 paper::
Here we show that instrumental advances in Raman optical activity, combined with quantum chemical computations, make it possible to determine the absolute configuration of (R)-[$$\ce{^2H1}$$, $$\ce{^2H2}$$, $$\ce{^2H3}$$]-neo... | {} |

RSA has not been cracked. No one has demonstrated practically viable computing that's anywhere in the realm of breaking RSA. There is no reason to change any of your practices. The first thing to understand is that D-Wave has a long history of repeatedly making bogus claims to the popular press. Experts... | {} |

## ajdirig Group Title Can anyone help find the inverse of the fxn: y=x^(2)+4x-6 one year ago one year ago
1. satellite73 Group Title
it is not a one to one function, so it is unlikely that it has an inverse
2. ajdirig Group Title
there are 2 inverses, depending on the chosen domain

## Local Lie Groups and Hilbert’s Fifth Problem
Lie Groups are mathematically “very nice” structures – they are analytic manifolds (real or complex) with a group structure such that multiplication and inversion are continuous. They are deeply related to infinitesimal symmetries; a group acting on a space can generally... | {} |
# Challenging
A ring of mass $$m$$ slides on a smooth vertical rod. A light string is attached to the ring and is passing over a smooth pulley over a smooth peg at a distance $$a$$ from the rod, and at the other end of the string is a mass $$M>m$$. The ring is held on a level with the peg and released. What is the dis... | {} |

# Why is this type of reductio ad absurdum not taught more?
I recently read in a book about a proof that Archimedes did. I don't remember the exact details and I don't have the book on me right now, but it involved proving an equality. So let's say proving that $A=B$. In order to do this, he first assumed that $A>B$ a... | {} |
