differs from its standard meaning as the real number 1, and is reinterpreted as an infinite terminating extended decimal that is strictly less than 1. [ 17 ] [ 18 ] Another elementary calculus text that uses the theory of infinitesimals as developed by Robinson is Infinitesimal Calculus by Henle and Kleinberg, originally published in 1979. [ 19 ]
The term differential is used nonrigorously in calculus to refer to an infinitesimal ("infinitely small") change in some varying quantity.For example, if x is a variable, then a change in the value of x is often denoted Δx (pronounced delta x).
In continuum mechanics, the infinitesimal strain theory is a mathematical approach to the description of the deformation of a solid body in which the displacements of the material particles are assumed to be much smaller (indeed, infinitesimally smaller) than any relevant dimension of the body; so that its geometry and the constitutive properties of the material (such as density and stiffness ...
However, the quantity dx 2 is infinitesimally small compared to dx; that is, the hyperreal system contains a hierarchy of infinitesimal quantities. Using hyperreal numbers for differentiation allows for a more algebraically manipulable approach to derivatives.
In mathematics education, calculus is an abbreviation of both infinitesimal calculus and integral calculus, which denotes courses of elementary mathematical analysis.. In Latin, the word calculus means “small pebble”, (the diminutive of calx, meaning "stone"), a meaning which still persists in medicine.
In thermodynamics, a reversible process is a process, involving a system and its surroundings, whose direction can be reversed by infinitesimal changes in some properties of the surroundings, such as pressure or temperature.

The infinitesimal character is the linear form on the center of the universal enveloping algebra of the Lie algebra of that the representation induces. This construction relies on some extended version of Schur's lemma to show that any in acts on as a scalar, which by abuse of notation could be written ().
