    en.wikipedia.org/wiki/Quartic_function

    Dividing by a 4, provides the equivalent equation x 4 + bx 3 + cx 2 + dx + e = 0, with b = ⁠ a 3 / a 4 ⁠, c = ⁠ a 2 / a 4 ⁠, d = ⁠ a 1 / a 4 ⁠, and e = ⁠ a 0 / a 4 ⁠. Substituting y − ⁠ b / 4 ⁠ for x gives, after regrouping the terms, the equation y 4 + py 2 + qy + r = 0 , where

    en.wikipedia.org/wiki/Standard_algorithms

    In elementary arithmetic, a standard algorithm or method is a specific method of computation which is conventionally taught for solving particular mathematical problems. . These methods vary somewhat by nation and time, but generally include exchanging, regrouping, long division, and long multiplication using a standard notation, and standard formulas for average, area, and vol

  5. cis (mathematics) - Wikipedia

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

    The cis notation is sometimes used to emphasize one method of viewing and dealing with a problem over another. [33] The mathematics of trigonometry and exponentials are related but not exactly the same; exponential notation emphasizes the whole, whereas cis x and cos x + i sin x notations emphasize the parts.

  6. Quartic equation - Wikipedia

    en.wikipedia.org/wiki/Quartic_equation

    Graph of a polynomial function of degree 4, with its 4 roots and 3 critical points. + + + + = where a ≠ 0. The quartic is the highest order polynomial equation that can be solved by radicals in the general case (i.e., one in which the coefficients can take any value).

  7. How to Solve It - Wikipedia

    en.wikipedia.org/wiki/How_to_Solve_It

    Pólya lays a big emphasis on the teachers' behavior. A teacher should support students with devising their own plan with a question method that goes from the most general questions to more particular questions, with the goal that the last step to having a plan is made by the student.

  8. Multiplication algorithm - Wikipedia

    en.wikipedia.org/wiki/Multiplication_algorithm

    The Toom–Cook method is one of the generalizations of the Karatsuba method. A three-way Toom–Cook can do a size-3N multiplication for the cost of five size-N multiplications. This accelerates the operation by a factor of 9/5, while the Karatsuba method accelerates it by 4/3.

  9. Extended real number line - Wikipedia

    en.wikipedia.org/wiki/Extended_real_number_line

    Extended real numbers (top) vs projectively extended real numbers (bottom). In mathematics, the extended real number system [a] is obtained from the real number system by adding two elements denoted + and [b] that are respectively greater and lower than every real number.
