Question

Please explain how to graph polar equations (In the simplest way) , for instance, 4 cos t

Answer 1

pick some obvious points that you can easily place about the graph then sketch a rough curve connecting them

Answer 2

r = 4cos(t)

t r
0 4
pi/2 0
pi -4
3pi/2 0

pi/4 2sqrt2 etc

Answer 3

How do you move from the origin if the radius is negative?

Answer 4

maybe a few more points ... but this is the idea

Answer 5

w/ respect to the angle

Answer 6

if the radius is negative you swing your angle then back up

Answer 7

-2, pi/3 for example
