  2. Trigonometric Functions • http://www.sosmath.com/trig/Trig2/trig2/trig2.html • This website presents the different trig functions and also explains the Pythagorean identities as well as the reciprocal identities. • Examples:

  3. BartholomeoPitiscus • http://www-groups.dcs.st-and.ac.uk/~history/Biographies/Pitiscus.html • The word trigonometry came from his book entitled “Trigonometria.” • In his book he described main definitions and theorems of plane and spherical trigonometry. • “Trigonometria” was only the first of the five books he published.

  4. Trig in the WORLD?? • http://www.mathscareers.org.uk/14_-_16/maths_in_everyday_life/trigonometry.cfm • Satellite navigation systems use trigonometry. • Trig is used because they need to know the precise distances between two points. • They use triangles with the corresponding angles and sides to find the distances. They also use variables a, b, and c when solving the equations.

  5. Sinusoidal Functions • http://www-ferp.ucsd.edu/najmabadi/CLASS/ECE60L/03-S/NOTES/math-2-sine.pdf • A sinusoidal function is made of a linear combination of Cosine and Sine functions. • Most Sine Functions begin at zero and Cosine begin at one.

  6. Interested in More Trig?? • http://www.ies.co.jp/math/products/trig/menu.html • This includes pictures, interactive motion pictures, and formulas. • Examples: They show how trig is involved in a ferris wheel and a crane which was very interesting to us.
