Leibnitz’s integral rule

The Leibnitz s integral rule gives a formula for differentiation of an integral whose limits are functions of the differential variable [2, 36, 8, 16, 9, 3, 28, 33, 18]. The formula is also known as differentiation under the integral sign. 

At the droplet surface, where r = R t), (40.25) may be shown as follows, using Leibnitz s integral rule, which relates the rate of change of the emulsion droplet radius with the mean radial mass velocity at droplet surface and droplet burning rate ...
