# Thread: Curve Intersection with Line and circle

1. ## Curve Intersection with Line and circle

Hi,
I need to find whether curve and circle intersecting and if so need intersection points.

Also i need to check intersection between curve and line and its intersection points.

Refer the attached drawing for clear picture. Intersection points are marked in red.

2. how is your curve given? Do you have an equation for it?

You will need to find the equations for the various curves and circle you have, set them equal to another and solve, hence you will have the points of intersection.

Do you have these equations?

4. I have circle and line equation but not having curve equation.

For curve i have the points(x,y) which i have marked in red.Is there any way to determine curve equation.
