Any number to the power of zero is 1. This can be proven by the laws of exponents, such that, for example, 52 / 52 = 25 / 25 = 1, because nx/nx = nx-x. Therefore, 160 = 1.
Imagine an n-sided polygon with a side length of x, then perimeter = nx. If sides are reduced to x/2 the perimeter becomes nx/2, ie it is halved.
According to the rules of exponents, nx/ny = nx-y. For example, 22/22 = 4/4 = 1. Subtracting the exponents gives 22-2 = 20. Therefore, 20 = 1.

There are many "attributes" of a cosine function. Some examples of attributes are as follows: For, constants a, b, n, y=a*cos(nx)+b has an amplitude of a, a period of 2pi/n, a range of [-a+b,a+b], a derivative of y'=-an*sin(nx).
