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)

step-by-step explanation:

1. the cylinder is a. 54

2.   a.108 /

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
