infinitesimal element in a sentence

Examples

1. This means that the spectral flux from a given infinitesimal element of area of the actual emitting surface of the black body, detected from a given direction that makes an angle with the normal to the actual emitting surface at, into an element of solid angle of detection centred on the direction indicated by, in an element of frequency bandwidth, can be represented as
2. In math and physics, " Moment of Inertia " is strictly the second moment of "'mass "'with respect to distance from an axis : I = \ textstyle \ int _ { Q } r ^ 2 \ mathrm dm, where r is the distance to some potential rotation axis, and the integral is over all the infinitesimal elements of " mass ", dm, in a three-dimensional space occupied by an object.
3. In each case the integral is over all the infinitesimal elements of " area ", dA, in some two-dimensional cross-section . " Moment of Inertia " is, strictly, the second moment of "'mass "'with respect to distance from an axis : I = \ int _ m r ^ 2 \ mathrm dm, where r is the distance to some potential rotation axis, and the integral is over all the infinitesimal elements of " mass ", dm, in a three-dimensional space occupied by an object.
