Secant (sec) - The secant of an angle is equal to the [math]{\text{Hypotenuse} \over \text{Adjacent}}[/math] or [math]\sec \theta = {1 \over \cos \theta}[/math]. Some of the definitions in trigonometry are: There are three main trigonometric ratios for right triangles, and three reciprocals of those ratios, making up a total of 6 ratios. The word "trigonometry" comes from two Greek words meaning "triangle measure." Trigonometry concerns the relationships among the sides and angles of triangles. The field emerged from applications of Geometry to astronomical studies in the 3rd Century BC 3. Their names and abbreviations are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).

Whats the requirement for measurement of the physical quantity? Hipparchus of Nicaea (c. 190 - c. 120 bc) was an astronomer, geographer, and mathematician. The definition of a triangle is any shape with three angles. Menelaus proved a property of plane triangles and the corresponding spherical triangle property known the regula sex quantitatum .Ptolemy was the next author of a book of chords, showing the same Babylonian influence as Hipparchus, dividing the circle into 360 and the diameter into 120 parts. Several summers ago, I created a set of printable radian sectors to illustrate what different amounts of radians looked like when graphed in standard form.
