- The curve \(C\) has equation \(y = \frac { \ln \left( x ^ { 2 } + 1 \right) } { x ^ { 2 } + 1 } , \quad x \in \mathbb { R }\)
- Find \(\frac { \mathrm { d } y } { \mathrm {~d} x }\) as a single fraction, simplifying your answer.
- Hence find the exact coordinates of the stationary points of \(C\).
