How To: Beat a polygraph or lie detector test

AntiPolygraph.org's George Maschke speaks with Nick Frost about how to fool a polygraph (lie detector) test in episode 5 of the tongue-in-cheek 2003 television series Danger: Incoming Attack. Note that the anal sphincter contraction, discussed as a polygraph countermeasure, while effective, is no longer recommended by AntiPolygraph.org, and alternative techniques such as mental countermeasures or tongue-biting are to be preferred.

Tips are shown throughout the video in the form of popups. Easy to understand.

How To: Use the laws of logarithms

ProfessorElvisZap teaches you about the laws of logarithms. When x is positive, meaning 0<x. x times y equals y times x. This is the commutative property. x times (y times z) equals (x times y) times z. This is the associative property. x times 1 equals x. This is the multiplicative property. x times x to the power of -1 equals 1. This is the multiplicative inverse property. You can use these properties with addition: a+b=b+a, (a+b)+c=a+(b+c), a+0=a and a+(-a)=0. A logarithm is a homomorphism...

How To: Apply the 1st Law of Exponents

In this video tutorial the author explains the concept of 1st Law of Exponents using an example. He shows that when we add polynomials the exponents does not change but when you multiply two polynomials their exponents change. He says that the new exponent is the sum of the first polynomial exponent and the second polynomial exponent. He further demonstrates this with a good example. This video clear shows with an example about the concept of the 1st Law of Exponents using it to multiply two ...

How To: Apply the 7th Law of Exponents

How To: Apply the 6th Law of Exponents

This is a video tutorial in the Education category where you are going to learn how to apply the 6th Law of Exponents. The 6th law of exponents says, to raise a product to a power, you can multiply each of its factors by the same power. For example if you have (acm) to the power x, that will be equal to the product of (a to the power x), (c to the power x) and (m to the power x). How is this done? (acm) to the power x is same as (a to the 1, c to the 1 and m to the 1). What we are doing is, w...

How To: Understand the basics of exponent laws

Before you can effectively use exponents, it is necessary to understand the laws behind them. First, in order to multiply a number raised to an exponent, by that number raised to another exponent, just add the exponents: for example, 2^5 * 2^2 is 2^(5+2), or 2^7. In short, a^m * a^n = a^(m+n). Similarly, dividing a number raised to an exponent by that number raised to another exponent can be done by subtracting the exponents: a^m / a^n = a^(m-n). To raise a number raised by an exponent to ano...

How To: Understand Newton's second law

In this tutorial the author explains the concept of Newton's Second Law of motion which states that force is equal to mass times acceleration. So the equation to compute force F is F = m * a, where m is the mass of the body and a is the acceleration produced by the force on that body. He explains that even our weight is our mass times the gravity. So now he explains that mass of a body is constant and only our weight changes depending up on the situation we are in. If you want a clear underst...
