As Tea puts it: "It's official; you're an idiot." Even the most basic of long division is portrayed as mind-bogglingly difficult, especially for parents helping their grade-schoolers do homework. The subject content (above) matches that set out in the Department for Education’s Mathematics GCSE subject content and assessment objectives document. While everything is explained well enough, the lumping together of too much information for difficult concepts makes it difficult to learn properly.

All you will need is a $10.00 calculator that does trig functions. (But, if you are reading this, you probably already have a computer!) I'll post the names of the first few people who correctly answer each question. When al-Khwarizmi's work was translated in Spain, the Arabic word shay was transcribed as xay, since the letter x was pronounced as sh in Spain. Joseph's take on " Ethnomathematics ": [Their work] takes on board some of the objections raised about the classical Eurocentric trajectory.

For example, to put of a negative number, you have to add π to the answer that you get (or 180° if in degrees); this is because arccot come from Quadrants I and II, and since we’re using the arctan function in the calculator, we need to add π. My favorite text on mathematical statistics is definitely the following. Other medieval Muslim mathematicians worthy of note include: the 9th Century Arab Thabit ibn Qurra, who developed a general formula by which amicable numbers could be derived, re-discovered much later by both Fermat and Descartes (amicable numbers are pairs of numbers for which the sum of the divisors of one number equals the other number, e.g. the proper divisors of 220 are 1, 2, 4, 5, 10, 11, 20, 22, 44, 55 and 110, of which the sum is 284; and the proper divisors of 284 are 1, 2, 4, 71, and 142, of which the sum is 220); the 10th Century Arab mathematician Abul Hasan al-Uqlidisi, who wrote the earliest surviving text showing the positional use of Arabic numerals, and particularly the use of decimals instead of fractions (e.g. 7.375 insead of 73⁄8); the 10th Century Arab geometer Ibrahim ibn Sinan, who continued Archimedes ' investigations of areas and volumes, as well as on tangents of a circle; the 11th Century Persian Ibn al-Haytham (also known as Alhazen), who, in addition to his groundbreaking work on optics and physics, established the beginnings of the link between algebra and geometry, and devised what is now known as "Alhazen's problem" (he was the first mathematician to derive the formula for the sum of the fourth powers, using a method that is readily generalizable); and the 13th Century Persian Kamal al-Din al-Farisi, who applied the theory of conic sections to solve optical problems, as well as pursuing work in number theory such as on amicable numbers, factorization and combinatorial methods; the 13th Century Moroccan Ibn al-Banna al-Marrakushi, whose works included topics such as computing square roots and the theory of continued fractions, as well as the discovery of the first new pair of amicable numbers since ancient times (17,296 and 18,416, later re-discovered by Fermat ) and the the first use of algebraic notation since Brahmagupta.

Write down from the tables the sines, cosines and tangents of the following angles: Check your results on your calculator. 2 Find two values of a between 0° and 180° when: 3 Find the angles between 0° and 180° whose cosines are: 4 Find e between 0° and 180° when: 5 Find the values of: (a) cosec 154° (c) cot 163.2° 6 Find e between 0° and 180° when: 8 Find the angles between 0° and 180° when: 77 We often need to use the trigonometrical ratios of the sum or difference of two angles.

(4) Statements that contain the word "including" reference content that must be mastered, while those containing the phrase "such as" are intended as possible illustrative examples. (1) Mathematical process standards. Trickier concepts appear under expandable headings like this. C.), since he measured an angle in terms of a fraction of a quadrant. [11] It seems that the systematic use of the 360° circle is largely due to Hipparchus and his table of chords.

These identities can be summarized by Napier's Rules of Circular Parts. This is very helpful in verifying you have the concepts and abilities mastered to work probelms. Next draw a line AD from A perpendicular to BC. You can see that: Don't worry if you can't remember these exact ratios... the simplest thing to remember is how to construct the special angle triangle... which is as easy as remembering a right angle triangle with a 45 degree angle and 2 sides of length 1... you can easily fill in the rest, and then work out the trig ratios yourself!

That's all for Right-Angled Triangles but what good is that if the triangle is not Right-Angled? So I just want to evaluate the right-hand side here. Type 625~ which will give the result 25 directly. Again, if (7) be divided by (8) tan" A = 1 - cos 2A 1 + cos 2A If 2A be replaced by a, formulae (4).

To help memorize the three Trig Ratios for Sine, Cosine, and Tangent, the Acronym “SOH – CAH – TOA” is used.
