The Christoffel symbols for cylindrical coordinates are a set of coefficients that describe how the basis vectors change across the coordinate system. Due to the orthogonal nature of the cylindrical coordinate system, the metric tensor is diagonal, simplifying the calculations significantly. The only non-zero Christoffel symbols are “the component of change in the azimuthal direction of the azimuthal basis vector that points in the radial direction” and “ the component of change in the azimuthal direction of the azimuthal basis vector as you move in the radial direction”, which arise solely from the change in the Azimuthal Basis Vector with respect to the radial coordinate. The negative sign in “the component of change in the azimuthal direction of the azimuthal basis vector that points in the radial direction” shows that the rate of change of the basis vector points inward toward the z-axis, while “the component of change in the azimuthal direction of the azimuthal basis vector as you move in the radial direction” represents the change in the magnitude of the Azimuthal Angle basis vector as the radial distance increases. Understanding these symbols is essential for performing calculations in curvilinear coordinate systems, such as finding the covariant derivative of a vector.
