Answer 2

Luke... I am your father...

Answer 3

fire away...

Answer 4

@dpaInc Name the polar symmetry of the graph with the polar equation r=2+2costheta

Answer 5

we gotta test for symmetry...
about polar axis... change the theta to -theta...

Answer 6

about the origin... change the r to -r

Answer 7

So when you change it and nothing happens, that means..

Answer 8

it's symmetrical if the equation is the same...

Answer 9

i forgot... 1 more

Answer 10

about the vertical line theta = pi/2, change theta to pi-theta

Answer 11

Pi/theta? Or pi minus theta?

Answer 12

for the last one, change theta to pi-theta
this checks for symmetry about the vetical line through the pole.

Answer 13

cosine is even so cos(theta) = cos(-theta)

Answer 14

HINT^^

Answer 15

got an answer?

Answer 16

Yes :D

Answer 17

it's symmetric about the.....

Answer 18

Polar axis: Symmetrical
Origin: Not symmetrical
Vertical line through the pole: Not symmetrical

Answer 19

very good my son....

Answer 20

go now and teach the ways of the force to others....

Answer 21

More questions though.
