Here's a small example this is not the real curve but a simple example I made for this question.
Here's the plot of a list with a point A of known coordinates.
Now I need to find if the point A is in the region bounded by the curve and the axes. I thought of creating a line passing through the origin and point A and finally intersecting the curve at a point B like in the figure below.
The next thing is to find the distance between A and the origin and compare it with the distance between B and the origin O. If OA is smaller than OB it means the point is in the region. But I don't know how to find the distance OB since I can't determine the coordinates of B. Is there anyway to do this? Are there any other suggested methods?Thank you.
