Question

rose?

Answer 1

r=4cos(4(0))=4
r=4cos(4(pi/2))=4
r=4cos(4(pi))=4
r=4cos(4(3pi/2))=6pi
r=4cos(4(2pi))=4

Answer 2

and then rose for part I

Answer 3

r=4cos(4(3pi/2))= 4 not 6pi

(so every value in the table is 4)

then you just need to plot/sketch, etc.

Answer 4

im having trouble with (4,2pi

Answer 5

oh nvm

Answer 6

here is the final

Answer 7

good then you just need to sketch something like

Answer 8

just a little neater, make sure all the petals stop at 4

Answer 9

okay got it now prt IV

Answer 10

if you notice, every pi/4 units there's a line of symmetry, so you would list out all the intervals of pi/4 starting from 0

there's also radial symmetry since every corresponding point is equidistant from the origin

Answer 11

0,pi,pi/2?

Answer 12

like that

Answer 13

3pi/2

Answer 14

actually come to think of it you can stop at pi

Answer 15

2pi

Answer 16

so 0, pi/4, pi/2, then 3pi/4

the line through 0 already includes pi
