Explain the cosine function and provide an example of how to use it to solve a math problem.

Explain the tangent function and provide an example of how to use it to solve a math problem.

Explain the Pythagorean theorem and how it can be used in solving trigonometry problems.

Introduce the concept of inverse trigonometric functions and provide an example of how to use them.

Provide an example problem using the sine function and guide students through the steps to solve it.

Provide an example problem using the tangent function and guide students through the steps to solve it.

Provide an example problem using the cosine function and guide students through the steps to solve it.

Provide an example problem using the Pythagorean theorem and guide students through the steps to solve it.

Provide an example problem using inverse trigonometric functions and guide students through the steps to solve it.

Summarize the main points of the lesson and ask students if they have any questions.

Give students time to work on the practice problems and provide assistance as needed.

Review the answers to the practice problems with students.

Engage students in a discussion about how trigonometry is used in everyday life.

End the lesson by summarizing the main points and encouraging students to continue practicing.

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
