- 1. ► Hello everybody. My name is Vincent, a lot of you know me as Vince. I take Intergraded Math II and my teacher’s name is Ms.Bush. The goal of the “Trigonometry Project” is to have an understanding and mastery of using Trigonometric ratios. This is a picture of my family and I.
- 2. ► Trigonometry is the branch of mathematics dealing with the relations of the sides and angles of triangles and with the relevant functions of any angles.► Some jobs using Trigonometry are carpeting, archeology, computer programming, graphic design, engineering, teaching and mathematics.
- 3. ► Slide 1: Labeling the Right Triangle► Slide 2: Explaining Sine► Slide 3: Explaining Cosine► Slide 4: Explaining Tangent► Slide 5: Conclusion
- 4. In A right triangle you have many differentparts.Hypotenuse: The longest side of a righttriangle, opposite the right angleAdjacent: The leg of the triangle that isright next to angle XOpposite: The leg of the triangle that isopposite of angle X
- 5. Sine Ratio: The ratio of the side of a right-angled triangle opposite to a specified angle to the hypotenuse. Sine is the angle oppostie of Angle X over the length of the Hypotenuse of the triangleExample: In the Triangle to the left the sine ratio of Angle Ais 6/10 because 6 is the opposite side of Angle A and 10 is theHypotenuse of the triangle.
- 6. Cosine Ratio: In a right triangle, the ratio of the length of the side adjacent to indicated angle over the length of the hypotenuse.Example: In the triangle to the left the cosine ratio of angle A is8/10 because 8 is the side adjacent to angle A and 10 is theHypotenuse of the triangle.
- 7. Tangent Ratio: In a right triangle, the ratio of the length of the side opposite the angle over the adjacent sideExample: In the triangle to the left the tangent ratio of Angle C is 8/68 is the length of the side opposite Angle C and 6 is the side adjacentof angle C.
- 8. ► Inconclusion I have learned a lot. I learned about the different carriers using Trigonometry. I also learned more about the different ratios of Trigonometry. I hope my presentation was helpful to you in helping you understand Trigonometry and the use of different Trigonometric ratios.
