High School Trigonometry Curriculum

Time4Learning’s online trigonometry course is one of five math courses offered at the high school level. This one-semester course is designed for students that have successfully completed a second year of algebra and desire to improve their analytic math abilities and understanding of trigonometry.

Our trigonometry curriculum is taught using a combination of multimedia lessons, instructional videos, quizzes, tests and both online and offline projects. All instruction is standards-based and helps to prepare students for college math courses.

On this page you will discover what topics are covered in a high school trigonometry course, learn more about the general objectives for trigonometry, and find out how families can use Time4Learning as their main curriculum for homeschool trigonometry or as a supplement to other programs.

What Do You Learn in Trigonometry?

The study of trigonometry is the study of distances. It uses geometrical constructions to determine the measurement of angles from the ratio of the lengths of the sides. Mathematicians have used trigonometry throughout history to determine distances between objects without having to measure them.

Some of the lessons included in Time4Learning’s online trigonometry curriculum for high school students are:

The Six Trigonometric Functions
Circular Functions
Graphs of Trigonometric Functions
The Law of Sines and Cosines
Trigonometric Identities
Trigonometric Equations
The Polar Coordinate System

Learning Objectives for High School Trigonometry

The topics that are covered in trigonometry encourage students to use problem solving and prepare them for future pursuits that may include STEM (science/technology/engineering/math) careers. Trigonometry has uses in such areas as surveying, navigation, drawing and architecture.

Throughout the trigonometry course, students will reach for the following goals:

Defining and applying the six trigonometric functions
Understanding the connection between trigonometric and circular functions
Graphing all six trigonometric functions and their transformations
Solving problems in oblique triangles using the Law of Sines, Cosines, and area formulas
Using the basic trigonometric identities to verify other trigonometric identities and to simplify complex trigonometry expressions
Solving trigonometric equations
Plotting points and graphing equations in the polar coordinate system
Using trigonometry concepts to solve real-world problems

Why Choose Time4Learning’s High School Trigonometry Curriculum?

Time4Learning’s one-semester trigonometry curriculum uses rich core content and interactive assignments and tools to enable students to apply knowledge in innovative ways. By breaking instruction into small chunks, pacing instruction properly, and capitalizing on multimedia instruction and graphic organizers to present information, students have an easier time retaining what they learn.

Some of the reasons that our trigonometry curriculum is popular with both parents and students include:

As a Full Curriculum

The course emphasizes higher order thinking skills, and uses practical, real-life math examples to teach the material.
Motivating, media-rich content keeps students engaged.
To accommodate students of all learning styles and diverse abilities, information is delivered in multiple formats including instructional video, animated models, graphs, and text.
The curriculum offers challenging content, relevant activities, assessments, and real-time feedback.
Each lesson includes assessments to determine whether students have mastered the lesson objectives.
A customizable assignment calendar helps students track the coursework they should be completing each day.
The system tracks student progress, and keeps printable reports that parents can turn into high school transcripts or include with homeschool portfolios.

As a Supplement

Powerful interactive instruction helps students build content knowledge and essential skills on individual topics.
Visual learners will especially benefit from on-screen teachers who present learning objectives, explain concepts, and model math strategies.
Students are taught step-by-step methods (identifying questions, clues, and strategies, and checking their work) when solving problems.
Students can work through the concepts sequentially or focus on specific areas where they need additional remediation.
The flexibility of the course allows families to use it as a supplement to other mathematics programs or even as a summer trigonometry course.
Detailed reporting tools help parents monitor student engagement, progress, and achievement along the way.
