Sin Cos Tan Teaching Trigonometry

Pre-requisite knowledge

Students who are new to trigonometry may find it helpful to first review the following concepts :

• The basics of algebra, including solving equations and inequalities.
• The basics of geometry, including the properties of triangles and circles.

These concepts can be found in a high school algebra and geometry textbook. Also, you can go online and check out Khan Academy, which has many free video lessons on these topics

What is trigonometry?

It is simply a way of describing the relationships between the sides and angles of triangles. By understanding how the sine, cosine, and tangent functions work, you will be able to find the missing side or angle of any triangle. This can be useful in a variety of real-world applications such as architecture, engineering, and navigation.

The sine function

The sine function is a trigonometric function that measures the ratio of the length of the opposite side to the length of the hypotenuse in a right triangle. It is often abbreviated as "sin." The sine function can be used to find the missing side or angle of a right triangle if you know the other two sides or angles.

The cosine function

The cosine function is a trigonometric function that measures the ratio of the length of the adjacent side to the length of the hypotenuse in a right triangle. It is often abbreviated as "cos." The cosine function can be used to find the missing side or angle of a right triangle if you know the other two sides or angles.

The tangent function

The tangent function is a trigonometric function that measures the ratio of the length of the opposite side to the length of the adjacent side in a right triangle. It is often abbreviated as "tan." The tangent function can be used to find the missing side or angle of a right triangle if you know the other two sides or angles.

Applications of trigonometry

Trigonometry has a wide variety of applications in the real world such as architecture, engineering, and navigation. For example, architects use trigonometry to design buildings that are structurally sound and aesthetically pleasing. Engineers use trigonometry to design bridges, roads, and other structures that are safe and efficient. Navigators use trigonometry to determine their location and to plot a course to their destination.

Conclusion

Trigonometry is a powerful tool that can be used to solve a variety of problems in the real world. By understanding the sine, cosine, and tangent functions, you will be able to find the missing side or angle of any triangle. This can be useful in a variety of fields, including architecture, engineering, and navigation.
