Holt McDougal is an American publishing company, a division of Houghton Mifflin Harcourt, that specializes in textbooks for use in high schools.. The Holt name is derived from that of U.S. publisher Henry Holt (1840–1926), co-founder of the earliest ancestor business, but Holt McDougal is distinct from contemporary Henry Holt and Company, which claims the history from 1866.
Harcourt (/ ˈ h ɑːr k ɔːr t /) was an American publishing firm with a long history of publishing fiction and nonfiction for adults and children. It was known at different stages in its history as Harcourt Brace, & Co. and Harcourt Brace Jovanovich. From 1919 to 1982, it was based in New York City. [1]
The lozenge shape is often used in parquetry (with acute angles that are 360°/n with n being an integer higher than 4, because they can be used to form a set of tiles of the same shape and size, reusable to cover the plane in various geometric patterns as the result of a tiling process called tessellation in mathematics) and as decoration on ...
[18] [19] Today, the degree, 1 / 360 of a turn, or the mathematically more convenient radian, 1 / 2 π of a turn (used in the SI system of units) is generally used instead. In the 1970s – 1990s, most scientific calculators offered the gon (gradian), as well as radians and degrees, for their trigonometric functions . [ 23 ]

For example, a circular disk of radius 1/2 can accommodate any plane curve of length 1 by placing the midpoint of the curve at the center of the disk. Another possible solution has the shape of a rhombus with vertex angles of 60° and 120° and with a long diagonal of unit length. [ 2 ]
The agreement, supported by 100% of HMH's creditors, highlighted a reduction in the senior debt to $3 billion from the current $5 billion, with new equity issued to the senior debt holders (including Paulson & Co. and Guggenheim Partners), [49] conversion of the $2 billion mezzanine debt into equity and warrant, receipt of $650m of new cash ...
which is exact for polynomials of degree 2n − 1 or less. This exact rule is known as the Gauss–Legendre quadrature rule. The quadrature rule will only be an accurate approximation to the integral above if f (x) is well-approximated by a polynomial of degree 2n − 1 or less on [−1, 1].
