Скачать или смотреть Unit 5 - Lesson 5.5 - Inverse Trig Functions

🎯 In this lesson, we explore how to graph and solve inverse trigonometric functions — including arccos, and arctan.
You’ll learn how each inverse trig function is defined, how to interpret their restricted domains and ranges, and how to use their graphs to solve equations and model real-world situations.

📌 What we cover:

Understanding inverse trig as “undoing” trig functions

Domains and ranges of arcsin, arccos, and arctan

How to graph inverse trig functions step-by-step (with attention to concavity & asymptotes)

Common mistakes and how to avoid them

📝 By the end of the video, you will be able to:

Graph inverse trigonometric functions accurately

Evaluate trig and inverse trig expressions (with attention to x-equivalent)

Use inverse trig to find missing angles in geometry and trigonometry problems
