## Module 4 - Topic 2 - Lesson 1 - Solving Trigonometric Equations

**Essential Question(s):**

How do you solve trigonometric equations?

What tools do you use to solve trigonometric equations?

**Follow the steps to complete your notes and review the content.**

**STEP 1: Preparation**

__Title__your spiral with the heading above,

__copy__the essential question(s), and draw your border line for the Cornell notes.

**STEP 2: Textbook**

__Answer__the follow questions by using your workbook.

__Read__more than enough to ensure a complete answer to the question.

Following a

__Cornell notes format__, the questions should be written in the left-hand column and with the answers to the right of the question.

Make sure to

__write enough to answer the question__.

__Activity 1.1__

- What are trigonometric equations?
- How do you know if the trig equation has a finite amount of solutions or an infinite amount of solutions?
- How do you write the solution to a trig equation with a domain of all real numbers?

__Activity 1.2__

- What are the inverse trig functions used for?
- How do you write the inverse functions of sine, cosine, and tangent?
- How do you know if you use the unit circle or calculator to solve a trigonometric function?
- How does a B ≠ 1 (horizontal dilation) affect your method of solving a trig equation?

**STEP 3: Self-check**

Perform a self-check after the lesson is completed in class by asking yourself the following question:

*"Can you*

__answer__the essential question(s)__completely__?"- Yes? Awesome job! You took
__effective notes__, and__paid attention__. You are on your way to success! :D - No? Ok. We all have struggles.
__Determine__why you said no, r__evise__your notes and self-check again.__Do not get discouraged__.
