What We Cover in Trigonometry

Every topic in the Trigonometry curriculum — taught for genuine understanding, not just test performance.

Unit 1
Right Triangle Trigonometry
SOH-CAH-TOA, inverse trig functions, and real-world applications including angles of elevation and depression.
Unit 2
Radian Measure
Converting between degrees and radians, arc length, and sector area.
Unit 3
The Unit Circle
Exact values at key angles, the relationship between trig functions and the unit circle, and reference angles.
Unit 4
Trig Functions & Graphs
Graphing sine, cosine, tangent — amplitude, period, frequency, phase shift, and vertical shift.
Unit 5
Inverse Trig Functions
Restricted domains, inverse sine, cosine, and tangent — evaluating and graphing inverse functions.
Unit 6
Trig Identities
Pythagorean, reciprocal, quotient, co-function, even/odd, sum/difference, and double-angle identities.
Unit 7
Solving Trig Equations
General solutions, solutions in a given interval, and combining identities to solve complex equations.
Unit 8
Laws of Sines & Cosines
Solving non-right triangles, ambiguous case (SSA), and applications in navigation and surveying.
Learning Outcomes

What Your Child Will Be Able to Do

Students leave the programme with complete mastery of trigonometric concepts, strong problem-solving skills, and full readiness for Precalculus and Calculus.

FOUNDATION
Unit Circle Mastery
Complete command of the unit circle — the foundation of all trig and essential for AP Calculus and Physics.
ADVANCED SKILLS
Identity Fluency
Trig identities are the most challenging skill in the course. Students build the pattern recognition to verify and apply them reliably.
VISUAL UNDERSTANDING
Function Graph Intuition
Understanding why trig graphs look the way they do — not just how to graph them — enables instant recognition in Calculus.
FUTURE READY
Precalculus & Calculus Ready
Students exit Trigonometry fully prepared for Precalculus and the trig-heavy chapters of AP Calculus.

Why Concept Mastery

Expert Trigonometry Instruction.

Trigonometry is a gateway course. Students need deep conceptual understanding of the unit circle, identities, and graphing — not just formulas.

Max 2 Students Per Group
Every Trigonometry group session is capped at 2 students — near-individual attention every session. Both students stay actively engaged and receive direct feedback.
Assignment Sheets Included
Curriculum-aligned Trigonometry assignment sheets reinforce session learning and build strong, consistent practice habits outside the classroom.
Monthly Progress Reports
Parents receive a detailed monthly written report tracking concept mastery, performance trends, and curriculum progress — specific, honest, and actionable.
Free 1-Hour Trial Class
Every student begins with a free 1-hour Trigonometry trial — meet the teacher, experience the teaching style, and decide with zero payment required.

Student Reviews

What Families Are Saying

Families trust Concept Mastery for expert Trigonometry support, conceptual clarity, and preparation that builds lasting confidence in math.

★★★★★
"My daughter could graph trig functions but had no idea why they looked the way they did. Her CM teacher rebuilt from the unit circle and it all clicked. She finished with a 95."

Parent · Grade 10 · Washington
★★★★★
"Trig identities destroyed my son's confidence. His CM teacher turned them into a pattern recognition exercise — once he saw the structure, he never failed another identity problem."

FAQ

Common Questions About Trigonometry

Why do students find Trigonometry so hard?
Trig requires a new kind of thinking — circular rather than linear. The unit circle, identities, and graphical transformations all challenge students who are used to algebra. We build all three explicitly.
Do you cover the unit circle thoroughly?
Yes — the unit circle is the foundation of our entire Trig programme. Students who own the unit circle find the rest of Trig dramatically more manageable.
How does Trig connect to Calculus?
Calculus uses trig functions constantly — derivatives of sin/cos, trig substitution in integration, and periodic functions throughout. Strong Trig preparation is directly correlated with AP Calculus performance.

Trigonometry Is the Gateway to Calculus. Build It Right.

The unit circle, trig identities, and graphical intuition — mastered deeply with a specialist teacher. Book your free assessment today.
