The unit quaternions give a group structure on the 3-sphere S 3 isomorphic to the groups Spin(3) and SU(2), i.e. the universal cover group of SO(3). The positive and negative basis vectors form the eight-element quaternion group .
Investigations was developed between 1990 and 1998. It was just one of a number of reform mathematics curricula initially funded by a National Science Foundation grant. The goals of the project raised opposition to the curriculum from critics (both parents and mathematics teachers) who objected to the emphasis on conceptual learning instead of instruction in more recognized specific methods ...
Students register for the exam through high schools that are members of the College Board. The test is composed of two sections: reading and Writing and Math. Each section has two modules. Each Reading and Writing module lasts 32 minutes, and each Math module lasts 35 minutes, for a total of 2 hours and 14 minutes.
In mathematics, a module is a generalization of the notion of vector space in which the field of scalars is replaced by a (not necessarily commutative) ring. The concept of a module also generalizes the notion of an abelian group, since the abelian groups are exactly the modules over the ring of integers. [1]
This is one-half of the harmonic mean of 6 and 4: 2·6·4 / 6 + 4 = 4.8. That is, the appropriate average for the two types of pump is the harmonic mean, and with one pair of pumps (two pumps), it takes half this harmonic mean time, while with two pairs of pumps (four pumps) it would take a quarter of this harmonic mean time.
We also saw a 50% increase in equipment utilization in pilot cells at Pratt's module center for the F135. ... Slide 8. Sales of $7.2 billion in the quarter were up 4% on an adjusted basis and 10% ...
We ended the quarter with cash and cash equivalents of $6.3 billion and debt of $6.3 billion. Cash from operations in the quarter was 925 million, capital expenditures were 381 million, and free ...
33-36 = Quarter 1, Quarter 2, Quarter 3, Quarter 4 (3 months each) The standard does not address 'named' dates so, for the purposes of CS1|2, Easter and Christmas are defined here as 98 and 99, which should be out of the ISO 8601 (EDTF) range of uses for a while. local_date_names_from_mediawiki is a boolean.
