Enlargement or extension of business transaction; especially, increase of the circulation of bank notes. 5. <mathematics> The developed result of an indicated operation; as, the expansion of (a + b)^2 is a^2 + 2ab + b^2. 6. The operation of steam in a cylinder after its communication with the boiler has been cut off, by which it continues to exert pressure upon the moving piston. 7. <astronomy> The enlargement of the ship mathematically from a model or drawing to the full or building size, in the process of construction. Expansion is also used adjectively, as in expansion joint, expansion gear, etc. Expansion curve, a curve the coordinates of which show the relation between the pressure and volume of expanding gas or vapor; especially.
