Thanks Bob.

Does the cross product work for 2D?

A circle with a radius of 10 has its center at (25, 0). There is a line/ray from the origin that touches the circle at one place. What is the area under the line from the origin up to the point?

I have come up with a solution using a line equation and the discriminant but I would like to solve it with vectors. I can only see that a dot product results in zero and that's as far as I can get.

Thanks.
