Geodesic motion of a point particle in Kerr geometry has three constants ofmotion, energy $E$, azimuthal angular momentum $L$, and Carter constant $Q$.Under the adiabatic approximation, radiation reaction effect is characterizedby the time evolution of these constants. In this letter we show that thescheme to evaluate them can be dramatically simplified.Comment: 5pages, no figure, accepted for publication in PT
