2. Constant (mathematics) - Wikipedia

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

   In mathematics, the word constant conveys multiple meanings. As an adjective, it refers to non-variance (i.e. unchanging with respect to some other value); as a noun, it has two different meanings: A fixed and well-defined number or other non-changing mathematical object, or the symbol denoting it.

3. Discrete calculus - Wikipedia

   en.wikipedia.org/wiki/Discrete_calculus

   It allows one to go from (non-constant) rates of change to the total change or vice versa, and many times in studying a problem we know one and are trying to find the other. Physics makes particular use of calculus; all discrete concepts in classical mechanics and electromagnetism are related through discrete calculus.

4. Related rates - Wikipedia

   en.wikipedia.org/wiki/Related_rates

   Construct an equation relating the quantities whose rates of change are known to the quantity whose rate of change is to be found. Differentiate both sides of the equation with respect to time (or other rate of change). Often, the chain rule is employed at this step. Substitute the known rates of change and the known quantities into the equation.

5. List of mathematical constants - Wikipedia

   en.wikipedia.org/wiki/List_of_mathematical_constants

   A mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. [1] For example, the constant π may be defined as the ratio of the length of a circle's circumference to ...

6. Rate of change - Wikipedia

   en.wikipedia.org/wiki/Rate_of_change

   Rate of change may refer to: Rate of change (mathematics), either average rate of change or instantaneous rate of change Instantaneous rate of change, rate of change at a given instant in time; Rate of change (technical analysis), a simple technical indicator in finance

7. Rate (mathematics) - Wikipedia

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

   In mathematics, a rate is the quotient of two quantities, 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 dividend (the fraction numerator) of the rate expresses the corresponding rate of change ...

9. Differential calculus - Wikipedia

   en.wikipedia.org/wiki/Differential_calculus

   In mathematics, differential calculus is a subfield of calculus that studies the rates at which quantities change. [1] It is one of the two traditional divisions of calculus, the other being integral calculus—the study of the area beneath a curve.
