Question

polar problem, r = 10 sin theta, change to cartesian equation,
i multiplied both sides by r, r^2 = 10 r sin theta , x^2 + y^2 = 10 y

Answer 1

oh i think i got a circle

Answer 2

10 sin(t) is a rose maybe?

Answer 3

subtract 10 y from both sides, complete the square

Answer 4

no we started with r = 10 sin theta

Answer 6

multiply both sides by r

Answer 7

its a circle offcentered

Answer 8

r^2 = 10 r sin theta, so x^2 + y^2 = 10 y

Answer 9

x^2 + y^2 - 10 y = 0, and complete the suqare

Answer 10

that looks good

Answer 11

how did you get a rose?

Answer 12

i dint; i was trying to remember what it looked like and apparentlly forgot :)

Answer 13
