The basepoint $p$ remains important because it determines the linear map $Df(p)$ used in the output pair. The derivative depends on the point at which it is evaluated.

Conditions: Applies to the basepoint derivative $df_p(v) = (q, Df(p)v)$.

Conditions: Applies to the basepoint derivative $df_p(v) = (q, Df(p)v)$.

The point $p$ serves as a basepoint. Retaining it motivates a basepoint-compatible notion of derivative, which is discussed next in the video.

Conditions: Applies to the first coordinate $p$ in $(p,v)\in T_p\mathbb{R}^n$
