what is the equation of a circle?

babynini · Answer

without using the polar forms of x and y
I have no idea.
Here's an example kindd of alike that my teacher used in class

babynini · Answer

Sorry it's super fuzzy o.o and barely readable. but if you zoom in super close maybe xD

babynini · Answer

I gave you all the info that the problem gives me, there's no numbers besides 10 and 0

amistre64 · Answer

still have to use theta?

im still trying to figure out the rules ...

how can we turn this into a cartesian equation, but still have to use theta?

amistre64 · Answer

(x-5)^2 + y^2 = 5  is the equation for our circle in cartesian

y = sqrt(5-(x-5)^2)
