Ch 31: ACT Math - Trigonometry: Tutoring Solution

About This Chapter

The Math - Trigonometry chapter of this ACT Prep Tutoring Solution is a flexible and affordable path to learning about trigonometry. These simple and fun video lessons are each about five minutes long, and they teach all of the operations involving trigonometry required for the ACT exam.

How it works:

  • Begin your ACT review or other math preparation work.
  • Identify the trigonometry concepts that you're stuck on.
  • Find fun videos on the topics you need to understand.
  • Press play, watch and learn!
  • Complete the quizzes to test your understanding.
  • As needed, submit a question to one of our instructors for personalized support.

Who's it for?

This chapter of our ACT prep tutoring solution will benefit any student who is trying to learn trigonometry and earn acceptable scores. This resource can help students including those who:

  • Struggle with understanding sine, cosine, basic trig identities, trigonometry functions on a scientific calculator, or any other trigonometry topic
  • Have limited time for studying
  • Want a cost effective way to supplement their ACT preparation
  • Prefer learning ACT topics visually
  • Find themselves struggling with the trigonometry portion of the review
  • Cope with ADD or ADHD
  • Want to get ahead in their ACT preparation
  • Don't have access to ACT review materials

Why it works:

  • Engaging Tutors: We make learning trigonometry simple and fun.
  • Cost Efficient: For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.
  • Consistent High Quality: Unlike a live ACT prep tutor, these video lessons are thoroughly reviewed.
  • Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Complete your trig review on the go!
  • Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.

Learning objectives:

  • Review sine, cosine and inverse trigonometry functions.
  • Learn to convert between radians and degrees.
  • Find out how to solve trigonometric equations for x.
  • Explore the relationship between trigonometry and the Pythagorean Theorem.
  • Review how to use a calculator in trigonometry.
  • Examine the difference between radians and degrees on a scientific calculator.

Trigonometry: Sine and Cosine

1. Trigonometry: Sine and Cosine

Learn an easy trick to help you solve trigonometry problems, including problems with sine, cosine and inverse trig functions. At the end of this lesson, you'll know what SohCahToa means and how to use it.

Converting Between Radians and Degrees

2. Converting Between Radians and Degrees

Angles can be measured in degrees or radians. This lesson will explore the difference and provide you with a simple calculation that can be used to convert degrees into radians and radians into degrees.

How to Solve Trigonometric Equations for X

3. How to Solve Trigonometric Equations for X

Adding trigonometric functions into standard algebra equations adds complexity. Learn how to solve trigonometric equations for x and how to use inverse operations to simplify equations.

List of the Basic Trig Identities

4. List of the Basic Trig Identities

There are specific trig functions that have very special and very simple relationships with each other. Learn the main one and how you can use it to understand the others.

Trigonometry and the Pythagorean Theorem

5. Trigonometry and the Pythagorean Theorem

Explore how the Pythagorean Theorem can be used in conjunction with trigonometric functions. In this lesson, take an inverse trigonometric function, and define all three sides of a right triangle.

Trigonometry Functions & Exponentials on a Calculator

6. Trigonometry Functions & Exponentials on a Calculator

Despite the fact that you've probably used a scientific calculator since middle school, it's really only in high school and college that you learn what all the keys are for. In this lesson, we look at trigonometric functions and exponential keys.

Trigonometry Functions & Exponentials on the CLEP Calculator

7. Trigonometry Functions & Exponentials on the CLEP Calculator

In this lesson, review how to use the history on the CLEP calculator as we calculate sines, cosines and the inverse trigonometric functions. Finish by exploring exponentials and logarithms.

Radians & Degrees on a Calculator

8. Radians & Degrees on a Calculator

While we may have a tendency to think of angles solely in terms of degrees, the truth is that radians offer a useful way of looking at them. However, being able to switch between the two is crucial for making the most of having a calculator.

Radians & Degrees on the CLEP Scientific Calculator

9. Radians & Degrees on the CLEP Scientific Calculator

In this lesson, we'll review online calculators, in particular the CLEP online calculator. Review the difference between radians and degrees, the order of operations and scientific notation on the CLEP calculator.
