(archaic, calculus) calculus / (mathematics, mathematical analysis) a systematic employment of infinitesimals that reduces calculus to algebra; nonstandard analysis.

(analytical chemistry) Any of several methods and techniques of analytical chemistry in which the amount of a substance in a sample is determined by weighing a precipitate, filtrate, residue etc after some physical or chemical process.

(analytical chemistry) Any of various analytical methods and techniques in which the amount of a substance in a sample is determined by measuring the volume of a liquid or gas; especially any method using titration.

(chemistry) Any of several similar radiochemical techniques of analysis in which a subatomic particle or gamma ray is captured by a nuclide to form a second stable nuclide which is then measured.

(mathematics) The branch of mathematics dealing with infinite-dimensional vector spaces, whose elements are actually functions, as well as generalizations such as Banach spaces and Hilbert spaces.

(mathematics) The branch of mathematics dealing with the real numbers and related structures.

(mathematical analysis) A study of the representation of functions or signals as the superposition of basic waves, involving the notions of harmonic functions, trigonometric series, Fourier series, Fourier transforms, almost periodic functions, and others.

The process of examining data to draw conclusions or insights, and determine cause-and-effect patterns between events; for example determining the safety and efficacy of new drugs by drawing out a probability as to whether the fact that a patient got better (or worse) was due to the drug or some other (perhaps random) factor.

(chemistry) The determination of the amounts of an element or compound in a sample. / Used other than figuratively or idiomatically: see quantitative, analysis.

(chemistry) The determination of the elements, functional groups or compounds present in a sample.
