Intersection of a Tangent and a Normal

Intersection of a Tangent and a Normal

If the tangent at parameter $$t_1$$ and normal at parameter $$t_2$$ are:

$$t_1y=x+at_1^2$$

$$y=-t_2x+2at_2+at_2^3$$

their intersection is obtained by solving the two linear equations.

Usage

- Used when a tangent and normal corresponding to different points intersect.
