YAYMATH In order to use rational functions in intermediate algebra, Robert Ahdoot begins by setting values to the functions f(x) and g(x). He then adds these functions together, with the equation (f+g)(x). After addition comes subtraction, using the equation (f-g)(x). And finally multiplication, which is (ftimesg)(x). This is a little more complicated, requiring distribution of a binomial across a polynomial, but it's clearly demonstrated and explained. This video explains what to do with add...

Central limit theorum is easily one of the most fundamental and profound concepts in statistics and perhaps in mathematics as a whole. In probability theory, the central limit theorum (CLT) states conditions under which the mean of a suffiently large number of independent random large variables (each with finite means and variance) will be normally distributed, approximately. Huh? If you are having trouble understanding central limit theorum and need help trying to solve it, check out this tu...

There's no doubt Kali has established itself as the most popular penetration distribution available. However, just because it's the fan favorite of beginners and security researchers doesn't make it right for everyone. Manjaro Linux is a beginner-friendly Arch-based distribution which can be easily weaponized with the Black Arch expansion, creating a friendlier first-time Arch experience.

One of the best parts about cooking is feeling the cold, hard steel of your cooking knife in your hand. The sleek skillful edge doesn't stand a change against any delicacy, unless it's dull. A dull knife takes the fun out of cooking and is actually more dangerous than a sharp knife, so take a moment to sharpen and care for your tools.
In 2013, Offensive Security released Kali Linux, a rebuild of BackTrack Linux derived from Debian. Since then, Kali has gone on to become somewhat of a standard for penetration testing. It comes preconfigured with a collection of tools accessible by a menu system, tied together with the Gnome desktop environment. However, Kali Linux isn't the only penetration-testing distribution available.
Kali Linux is the obvious first choice of an operating system for most new hackers, coming bundled with a curated collection of tools organized into easy-to-navigate menus and a live boot option that is very newbie-friendly. But Kali isn't the only distribution targeted at pentesters, and many exciting alternatives may better fit your use-case. We've already covered BlackArch Linux, now it's time to talk about Parrot Security OS.
Apple is widely known for keeping a tight grip on iOS, disallowing open-source and third-party downloads. While there are many reasons for this, the three most frequently referenced are quality control, malware prevention, and of course—money.
Kali Linux is probably the most well-known hacking distribution among penetration testers. However, there are alternative distros which offer versatility and advanced package management systems that are absolutely worth considering.
Kali Linux is established as the go-to operating system for penetration testing, but in its default configuration, it's less than ideal for regular desktop use. While in many scenarios, a live boot or virtual environment can resolve these issues, in some situations, a full installation is better. A few simple changes can be made to a Kali Linux desktop to make it safer to use in this environment.
