Question

Don't get this step. x^2+y^2=3y. then it says x^2+(y-3/2)^2= (3/2)^2 . where does the 3/2 come from?

Answer 1

I should mention this is finding a Cartesian equation. r=3sin(theta)

Answer 2

Took the 3y to the other side and complate that square.

Answer 3

they seen it was a cirlce so they wrote it in the standard from of a circle

Answer 4

x^2+y^2-3y=0
(x-0)^2+y^2-3y+(3/2)^2=(3/2)^2
(x-0)^2+(y-3/2)^2=(3/2)^2

Answer 5

...This Calculus thing would be a whole lot easier if I ever actually learned Algebra.

Thanks guys!
