The idea becomes clearer by considering the general series 1 − 2x + 3x 2 − 4x 3 + 5x 4 − 6x 5 + &c. that arises while expanding the expression 1 ⁄ (1+x) 2, which this series is indeed equal to after we set x = 1.
Sahih al-Bukhari is divided into 97 books. Books 2–33 are about the Pillars of Islam. Books 34–55 are about finance. The remaining books are not arranged according to some identifiable theme, although the very first and last books are for opening the collection (with a book on the first revelation) and closing it (with a book on Tawhid).

To solve the third-degree equation x 3 + a 2 x = b Khayyám constructed the parabola x 2 = ay, a circle with diameter b/a 2, and a vertical line through the intersection point. The solution is given by the length of the horizontal line segment from the origin to the intersection of the vertical line and the x -axis.
Muhammad Ibrahim Husayn Shadhili Qutb [a] (26 April 1919 – 4 April 2014) was an Islamic scholar and the younger brother of the Egyptian revolutionary Sayyid Qutb. After his brother was executed by the Egyptian government, Muhammad moved to Saudi Arabia , where he promoted his brother's ideas.
Supplementary exercises at the end of each chapter expand the other exercise sets and provide cumulative exercises that require skills from earlier chapters. This text includes "Functions and Graphs in Applications" (Ch 0.6) which is fourteen pages of preparation for word problems. Authors of a book on finite fields chose their exercises freely ...
2. Denotes the additive inverse and is read as minus, the negative of, or the opposite of; for example, –2. 3. Also used in place of \ for denoting the set-theoretic complement; see \ in § Set theory. × (multiplication sign) 1.

Kashf al-Zunun 'an Asami al-Kutub wa al-Funun (The Removal of Doubt from the Names of Books and the Arts) is a bibliographic encyclopedia of books and sciences compiled by Turkish polymath Kâtip Çelebi.
In planar dynamics a pole is a center of rotation, the polar is the force line of action and the conic is the mass–inertia matrix. [4] The pole–polar relationship is used to define the center of percussion of a planar rigid body. If the pole is the hinge point, then the polar is the percussion line of action as described in planar screw theory.
