1. ADVANCED MATH/TRIG CHASTITY REYNOLDS

2. WHAT IS TRIGONOMETRY?  Trigonometry is “the branch of mathematics that deals with the relations between the sides and angles of plane or spherical triangles, and the calculations based on them.” (“Trigonometry”)

3. WHEN/WHERE DID TRIG ORIGINATE?  Connected with math and astronomy  “first work on trigonometric functions related to chords of a circle.” (“The Trigonometric Functions”)  Originated from a man named Hipparchus  Greek mathematician  “The first known table of chords were produced… in about 140 BC.” (“The Trigonometric Functions”)  Many others followed Hipparchus’s method

4. MATHEMATICIANS WHO DISCOVERED TRIG.  Hipparchus:  Greek mathematician  Menelaus: 100 AD  Rome  “Producing six books of tables of chords which have been lost but his work on spherics has survived and is the earliest known work on spherical trigonometry.” (“The Trigonometric Functions“)  Regula sex quantitatum  Ptolemy  Influenced by Hipparchus  “Calculated chords by first inscribing regular polygons of 3,4,5,6, and 10 sides in a circle.” (“The Trigonometric Functions“)  Used to calculate degrees to find chords

5. MATHEMATICIANS WHO DISCOVERED TRIG.  Hindus:  In about 500, Aryabhata created sine tables  Brahmagupta in 628, created sine tables also  Bhaskara in 1150, showed methods to construct a table of sines for any angle.  Arabs  “by 980 Abu’l-Wafa knew..” that sin2x=2 x cos x. (“The Trigonometric Functions“)  Copernicus, Rheticus, and Regiomontanus also contributed by writing books that were about tables of sines and cosines and “contained work on planar and spherical trigonometry…” (“The Trigonometric Functions“)

6. REAL-WORLD APPLICATIONS/SCENARIOS THAT INVOLVE TRIG. ÷ Measuring the floor of a room that is shaped in a circle, to know the measures so that you are able to put down missing carpet. ÷ “Computers utilize trigonometry to establish the shades and colors of images on a screen.” (“Modern Uses of Trigonometry”) ÷ “MRI machines scan your body and display the color image on a computer screen.” (“Modern Uses of Trigonometry”) ÷ “Medical professionals use the results to determine the cause and location of cancers and tumors” (“Modern Uses of Trigonometry”)
