Name 2 characteristics of the Polar Coordinate System

.I will list some characteristics:

The polar coordinates only uses 2 variables:

r, that is the radius and can have values equal or greater than zero, this is:

0 ≤  r

and θ, which is the angle, we measure the angle from the x-axis and it grows counterclockwise. An interesting this about this variable is that, while we can have any value for θ, we have that θ is a periodic variable with a period of 2*pi

So if we have θ = A, is the same that having θ = A + n*2*pi, where n can be any integer number

And we can transform the rectangular cordinates to polar cordinates by:

x = r*cos(θ)

y = r*cos(θ)

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
