How do I find the most right point on a circle? [closed]
$begingroup$
I have given the center point and the radius of a circle but i am interested in the most right point which is lying on that circle.
edited:
thanks for the comments. I have the central point c and have the radius r as well. And my question was what is the equation to get the most right point p on the circle surrounding the center by the given radius.
r = sqrt((p1-c1)(p1-c1) + (p2-c2)(p2-c2))
then i am looking for the (p1,p2) point
At the end I found it out with the help and hint from you. As I mentioned I had the central point C and the radius R and I was looking for the most right point P on the edge of the circle. My approach what finally helped was to calculate a square around the circle (bounding box) and take as x coordinate for the P point the x coordinate of the top right corner of that bounding box, and the y coordinate for the P point the y of the C point.
Thanks for every help, as far as it showed me the right direction.
P(x,y)=(xC,yC)+v⃗ R <--- this helped also as the v⃗ R is a normal vector on the right edge of the mentioned bounding box.

I assume you have the equation. Set $y$ equal to the height of the center and solve for $x$. If that's not what you want, edit the question to tell us what you do know.

If i understand it right:Center $vec{c}$, radius $r$, $vec{p}$ the point you are looking for. $vec{p} = vec{c} + r vec{e_x}$, where $vec{e_x}$ is the unit-vector in x-direction.

HINT
Assuming the center at $C(x_C,y_C)$ any other point on the circle with radius $R$ can by obtained by
$$P(x,y)=(x_C,y_C)+vec v_R$$
with $|vec v_R|=R$.
