Rate of convergence In numerical analysis (a branch of mathematics), the speed at which a convergent sequence approaches its limit is called the rate of convergence. Although strictly speaking, a limit does not give information about any finite first part of the sequence, this concept is of practical importance if we deal with a sequence of successive approximations for an iterative method, as then typically fewer iterations are needed to yield a useful approximation if the rate of convergence is higher.

Rate distortion theory Rate distortion theory is a major branch of information theory; it addresses the problem of determining the minimal amount of entropy (or information) R that should be communicated over a channel, so that the source (input signal) can be approximately reconstructed at the receiver (output signal) without exceeding a given distortion D.
Rate equation According to IUPAC Gold BookIUPAC Gold Book definition of rate law the rate law or rate equation for a chemical reaction is an equation which links the reaction rate with concentrations or pressures of reactants and constant parameters (normally rate coefficients and partial reaction orders). To determine the rate equation for a particular system one combines the reaction rate with a mass balance for the system.

Rate of convergence In numerical analysis (a branch of mathematics), the speed at which a convergent sequence approaches its limit is called the rate of convergence. Although strictly speaking, a limit does not give information about any finite first part of the sequence, this concept is of practical importance if we deal with a sequence of successive approximations for an iterative method, as then typically fewer iterations are needed to yield a useful approximation if the rate of convergence is higher.

Rate of return on investment Investors frequently ask how they can calculate the return their portfolio is generating. This calculation is a calculation of actual returns realized (past tense: ex post), not the returns expected (future tense: ex ante using NPV or IRR methods).
Rate risk In finance, rate risk is the risk of losses caused by interest rate changes. The prices of most financial instruments, such as stocks and bonds move inversely with interest rates, so investors are subject to capital loss when rates rise.
Rate tart Coined in a 2004 survey, the term 'Rate Tart' refers to the growing number of consumers who use credit cards to get interest free loans. Rate Tarts move the balance of their debt onto a credit card that offers an interest free period, moving it again when the introductory offer expires so that they never pay any interest.
Rate theory (hearing) Rate theory is a theory of hearing which states that our perception of sound depends on the rate at which neurons signal the frequency of each component. Therefore, the pitch of a pure tone would be determined by the rate at which the neurons fire.

Rational mapping In mathematics, a rational mapping is a concept of algebraic geometry which resembles that of a partial function. Loosely speaking, a rational map is a regular map of algebraic varieties which is only defined on an open subset of the domain; the fact that this does, in fact, carry significant geometric data reflects the phenomenon that algebraic geometry is fundamentally more “rigid” than other geometries, for example differential geometry.
