| A Non-Reintersecting Tangent (Posted on 2016-02-24) |
 |
Most tangent lines to the curve y=1/(x^2+1) reintersect the curve at another point. Three of these tangent lines do not. One of them is the trivial line y=1. Find the other two.

The tangents are the two lines tangent at the curve's two inflection points. Charlie derives them here. |
