This is one of my exercise on my notes. I am still stuck and hope someone can help.
We have $p \in M$ and $V,W\in ˇT_p M$.
Compute the Jacobi fields of the following geodesic variations at $s=0$. $γ_s(t) = exp_{η(s)}(tV_{η(s)})$, where $η(s) = exp_p (sW)$ and $V_{η(s)} ∈ T_{η(s)}M$ is the parallel transported version of V along η.
