2. Rate (mathematics) - Wikipedia

   en.wikipedia.org/wiki/Rate_(mathematics)

   In mathematics, a rate is the quotient of two quantities in different units of measurement, often represented as a fraction. [1] If the divisor (or fraction denominator) in the rate is equal to one expressed as a single unit, and if it is assumed that this quantity can be changed systematically (i.e., is an independent variable ), then the ...

3. Everyday Mathematics - Wikipedia

   en.wikipedia.org/wiki/Everyday_Mathematics

   Everyday Mathematics. Everyday Mathematics is a pre-K and elementary school mathematics curriculum, developed by the University of Chicago School Mathematics Project (not to be confused with the University of Chicago School of Mathematics). The program, now published by McGraw-Hill Education, has sparked debate.

4. Proportional–integral–derivative controller - Wikipedia

   en.wikipedia.org/wiki/Proportional–integral...

   Fundamental operation A block diagram of a PID controller in a feedback loop. r(t) is the desired process variable (PV) or setpoint (SP), and y(t) is the measured PV.. The distinguishing feature of the PID controller is the ability to use the three control terms of proportional, integral and derivative influence on the controller output to apply accurate and optimal control.

5. Frequency (statistics) - Wikipedia

   en.wikipedia.org/wiki/Frequency_(statistics)

   Frequency distribution table. A frequency distribution table is an arrangement of the values that one or more variables take in a sample. Each entry in the table contains the frequency or count of the occurrences of values within a particular group or interval, and in this way, the table summarizes the distribution of values in the sample.

6. International System of Units - Wikipedia

   en.wikipedia.org/wiki/International_System_of_Units

   The International System of Units, internationally known by the abbreviation SI (from French Système international d'unités ), is the modern form of the metric system and the world's most widely used system of measurement. Coordinated by the International Bureau of Weights and Measures (abbreviated BIPM from French: Bureau international des ...

7. Logarithm - Wikipedia

   en.wikipedia.org/wiki/Logarithm

   In mathematics, the logarithm is the inverse function to exponentiation. That means that the logarithm of a number x to the base b is the exponent to which b must be raised to produce x. For example, since 1000 = 103, the logarithm base of 1000 is 3, or log10 (1000) = 3.

8. Lists of mathematics topics - Wikipedia

   en.wikipedia.org/wiki/Lists_of_mathematics_topics

   Information theory is a branch of applied mathematics and Social science involving the quantification of information. Historically, information theory was developed to find fundamental limits on compressing and reliably communicating data. Signal processing is the analysis, interpretation, and manipulation of signals.

9. Mathematical table - Wikipedia

   en.wikipedia.org/wiki/Mathematical_table

   Mathematical tables are lists of numbers showing the results of a calculation with varying arguments.Trigonometric tables were used in ancient Greece and India for applications to astronomy and celestial navigation, and continued to be widely used until electronic calculators became cheap and plentiful in the 1970s, in order to simplify and drastically speed up computation.
