(mechanics) A type of differential that allows its output shafts to rotate at different speeds but can limit the maximum difference in angular velocity between the output shafts, allowing greater torque to be applied to the slower-spinning shaft(s) and generally resulting in better traction than older-design differentials.

(mathematics, complex analysis, of a function) That is differentiable and satisfies the Cauchy-Riemann equations on a subset of the complex plane.

(mathematics) That has a quasi-derivative.

plural of differential geometry

A branch of psychology focusing on how and why individuals differ in their behaviour.

(mathematics) The equation that defines the Legendre polynomials: d/dx[(1-x²)d/dxP_n(x)]+n(n+1)P_n(x)=0.

(mathematics, mathematical analysis) An operator defined as a function of the differentiation operator (the operator which maps functions to their derivatives).

plural of differential operator

(automotive, mechanical engineering) Steering by means of driving the wheels or treads on one side of a vehicle faster than those on the other side, or driving the wheels or treads on one side in the forward and on the other side in the reverse direction.

(mathematics) an infinitesimal change in a variable in a partial derivative, or the result of partial differentiation
