Question

The graph shown represents which of the following polar equations?



A. r = 3 + 3sin∂
B. r = 4 + 3sin∂
C. r = 5cos(3∂)
D. r = 2 + 5sin∂

Answer 1

I have no idea how to do this.. can someone help?

Answer 2

my guess is B though

Answer 3

if thats the case then A?

Answer 4

sorry... i was looking at something else.. forget what i said..

Answer 5

i would choose B...

Answer 6

here's why...

Answer 7

okay thank you :)

Answer 8

the closest the graph gets to the pole is 1... and since sin and cosine has ranges between -1 and 1, only B will get you a minimum of 1.
