## Main Question or Discussion Point

This is essentially a "homework question", but I'm not looking for an explicit solution so I have posted it here.

1. Homework Statement

Find a simplified expression for the Riemann tensor in terms of the connection in normal coordinates.

2. Homework Equations

Riemann tensor = (derivative of connection term) - (derivative of connection term) - (connection term)(connection term) - (connection term)(connection term)

3. The Attempt at a Solution

My solution is

Riemann tensor = (derivative of connection term) - (derivative of connection term)

, where I have used the fact that the connections evaluated at point P are all 0, but their derivatives are not necessarily 0.

My problem is that 3 MARKS are allocated to this question (from a possible 60 marks in a 2 hour paper), and that this looks far too simple a solution for 3 marks.

What am I missing?
