 Since the subspace $C$ is transpose-invariant, we also have
 \[ \mathcal{P}(X^\top) = \mathcal{P}(X)^\top. \]
 We can now see that
-\[

 \begin{align*}
-d\Delta & = -\mathcal{P}(dA^\top Q A + A^\top Q\,dA) \\
-& = -\big[\mathcal{P}(A^\top Q\,dA)^\top + \mathcal{P}(A^\top Q\,dA)\big].

 Plugging this into our formula for $df$, and recalling that $\Delta$ is symmetric, we get
