omgosh so confusing...

Answer 4

i know can you help

Answer 5

well... I'm have almost no clue at this... and I'm not even good at this... but I think its A or D... lol don't believe me but it might lead you to think on those... trust me, I don't know

Answer 6

please help @sooobored

Answer 7

polar coordinates (r,theta) arent that hard,
I assume you understand Cartesian coordinates which is (x,y,z)

Polar coordinates uses the distance from the center which we call the radius and the angle it makes based off a given reference point (usually the positive x-axis on a graph)
Cartestian coordinates uses distances and right angles in order to determine specific location in space

Answer 8

hopefully that attaches correctly

for understanding the relevance of pi

Answer 9

we consider a full revolution or 360 degrees as being 2pi

so 180 degree is pi, 90 is pi/2, 45 is pi/4
180 divided by 5 = 32 degrees which is equal to pi/5
so pi/5 might make the angle look something like this

Answer 10

positive angles go around in a counter clockwise direction as shown in the picture above

negative angles go around in a clockwise motion as shown here as -pi/5

Answer 11

now remember we mentioned how 2pi is a full revolution/circle or 360 degrees,
this means any angle plus 2pi is the same angle

on a side note 2pi is one full revolution, 2* 2pi is two full revolutions, 5*2pi is five full revolutions, hence n*2pi is n full revolutions where n can only be whole numbers(i.e. n= 0,1,2,3...)

Answer 12

now explaining how the radius is used,

radius is the distance away from the center/origin (0,0)

if we were to consider an angle of zero and a distance of x, it would have the ordered pair of (x,0) and look something like this

Answer 13

so its kind of the same if you were plotting on the x-axis in cartesian coordinates(x,y)

now say we want to plot (x,pi/4) -which is 45 degrees
it would look something like this
