    Strong performance in Algebra I, Geometry, and Algebra II predict good grades in university-level Calculus even better than taking Calculus in high school. [44] Another issue with mathematics education has been integration with science education. This is difficult for public schools to do because science and math are taught independently.

    For example, the logical independence of the parallel postulate was established, relative to the other axioms of Euclidean geometry, during the nineteenth century. The independence results most of interest in contemporary mathematics are for the most part relative to the axioms of ZFC set theory , the de facto standard foundational system.

    The number of degrees of freedom is equal to the number of cells rc, minus the reduction in degrees of freedom, p, which reduces to (r − 1)(c − 1). For the test of independence, also known as the test of homogeneity, a chi-squared probability of less than or equal to 0.05 (or the chi-squared statistic being at or larger than the 0.05 ...

    The intervals of 5-limit just intonation (prime limit, not odd limit) are ratios involving only the powers of 2, 3, and 5. The fundamental intervals are the superparticular ratios 2/1 (the octave), 3/2 (the perfect fifth) and 5/4 (the major third). That is, the notes of the major triad are in the ratio 1:5/4:3/2 or 4:5:6.

    The term algebra is derived from the Arabic word al-jabr meaning 'the reunion of broken parts' that he used for naming one of these methods in the title of his main treatise. [31] [32] Algebra became an area in its own right only with François Viète (1540–1603), who introduced the use of variables for representing unknown or unspecified ...

    en.wikipedia.org/wiki/Five_lemma

    The method of proof we shall use is commonly referred to as diagram chasing. [1] We shall prove the five lemma by individually proving each of the two four lemmas. To perform diagram chasing, we assume that we are in a category of modules over some ring , so that we may speak of elements of the objects in the diagram and think of the morphisms ...
