Glossary

Angles & radians

A central idea in the intermediate Trigonometry path, covered in the module of the same name.

Example: apply Angles & radians to a small, familiar case step by step, then check your reasoning against the walkthrough.

Right-triangle ratios

A central idea in the intermediate Trigonometry path, covered in the module of the same name.

Example: apply Right-triangle ratios to a small, familiar case step by step, then check your reasoning against the walkthrough.

The unit circle

About the Trigonometry curriculum

The Trigonometry curriculum is a complete, self-paced course in mathematics, organised into 3 progressive levels and 9 modules. It opens with Foundations of Angles & radians and Core methods in Right-triangle ratios, moves through Applying The unit circle and finishes with expert-level work on Leading practice in Applications in waves & circles and Mastering Inverse functions.

Across the whole path you work through 27 individual topics — from Angles & radians and Putting angles & radians to work at the start to Putting inverse functions to work and Checking your understanding of inverse functions by the end. The levels are estimated at 6 weeks · about 24 hours, 8 weeks · about 32 hours and 10 weeks · about 40 hours. Each level assumes the one before it, so you can work straight through from Intermediate to Expert, or start at the level that matches what you already know.

It suits analysts, researchers and students who need to reason with numbers and defend a conclusion, not just run a tool. The emphasis is on interpretation: every technique is introduced with the question it answers, the assumption it needs and the way it fails, so you can apply it to unfamiliar data.

Every module pairs a written summary with a worked example, a short quiz to check the idea landed, and a project brief drawn from real practice. You are never asked to take a concept on trust: the reasoning, the common mistakes and the situations where the approach stops working are all laid out, so you finish a module able to explain the idea rather than only recognise it.

What you’ll be able to do

By the end of the Trigonometry path you should be able to work confidently with:

How the Trigonometry curriculum is structured

Intermediate 6 weeks · about 24 hours 3 modules 9 topics

Intermediate Trigonometry

Start with Angles & radians, Right-triangle ratios and The unit circle. Each module explains the idea, shows a worked example and ends with a short project, so Trigonometry becomes something you can do rather than something you have only read about.

Modules: Foundations of Angles & radians · Core methods in Right-triangle ratios · Applying The unit circle

  • Angles & radians: Angles & radians is where many Trigonometry learners first get stuck, so the module slows down, isolates the difficult step and rebuilds it with you.
  • Putting angles & radians to work: This module treats Angles & radians as a tool: the question it answers, what it assumes, and what a correct use of it looks like in Trigonometry.
  • Checking your understanding of angles & radians: Angles & radians is where many Trigonometry learners first get stuck, so the module slows down, isolates the difficult step and rebuilds it with you.

Project: Write a one-page explanation of Angles & radians in your own words, with an example you chose yourself, and test it against the module checklist.

Advanced 8 weeks · about 32 hours 3 modules 9 topics

Advanced Trigonometry

Build on the intermediate level through Trigonometric graphs, Identities and Solving triangles. The emphasis shifts from knowing the ideas to choosing between them — trade-offs, failure modes and the reasoning behind each decision.

Modules: In depth Trigonometric graphs · Patterns and trade-offs in Identities · Scaling Solving triangles

  • Trigonometric graphs: Here Trigonometric graphs becomes a design decision. You compare alternatives, justify a choice and test it against a harder problem.
  • Hands-on: trigonometric graphs: Trigonometric graphs is pushed past the textbook case: competing approaches, their trade-offs and the situations where each one breaks down.
  • Checking your understanding of trigonometric graphs: Here Trigonometric graphs becomes a design decision. You compare alternatives, justify a choice and test it against a harder problem.

Project: Produce a short case analysis in which Trigonometric graphs drives the recommendation, including the alternatives you rejected and why.

Expert 10 weeks · about 40 hours 3 modules 9 topics

Expert Trigonometry

Work at the edge of Trigonometry through Law of sines & cosines, Applications in waves & circles and Inverse functions. The modules assume fluency and ask for judgement: designing, critiquing and defending work at a professional standard.

Modules: Frontiers of Law of sines & cosines · Leading practice in Applications in waves & circles · Mastering Inverse functions

  • Law of sines & cosines: This module asks you to critique and extend Law of sines & cosines rather than simply apply it, producing work another expert could review.
  • Putting law of sines & cosines to work: At expert level Law of sines & cosines is treated as a field of judgement: current practice, contested positions and the evidence behind each.
  • Checking your understanding of law of sines & cosines: This module asks you to critique and extend Law of sines & cosines rather than simply apply it, producing work another expert could review.

Project: Write a professional-standard brief on Law of sines & cosines — argument, evidence, limitations — plus a plan for taking the work further.

How to study Trigonometry, phase by phase

  1. 1

    Phase 1 — Intermediate

    Set aside around 6 weeks · about 24 hours. Work through 3 modules, starting with Foundations of Angles & radians and Core methods in Right-triangle ratios.

  2. 2

    Phase 2 — Advanced

    Set aside around 8 weeks · about 32 hours. Work through 3 modules, starting with In depth Trigonometric graphs and Patterns and trade-offs in Identities. Finish the phase by completing the project brief: Produce a short case analysis in which Trigonometric graphs drives the recommendation, including the alternatives you rejected and why.

  3. 3

    Phase 3 — Expert

    Set aside around 10 weeks · about 40 hours. Work through 3 modules, starting with Frontiers of Law of sines & cosines and Leading practice in Applications in waves & circles. Finish the phase by completing the project brief: Write a professional-standard brief on Law of sines & cosines — argument, evidence, limitations — plus a plan for taking the work further.

  4. 4

    Phase 4 — Consolidate

    Return to the sections that felt weakest, redo their quizzes from memory, and rebuild the Write a one-page explanation of Angles & radians in your own words, with an example you chose yourself, and test it against the module checklist. without following along. Explaining Trigonometry to someone else in plain language is the clearest signal that the Expert level has landed.

Once you have finished, the Trigonometry path is a reasonable foundation for analytics, data science, research and quantitative roles. Because the curriculum is generated and kept as a structured outline rather than fixed videos, you can revisit any module, regenerate the outline at a different depth, or save it to your library and work through it over weeks rather than in one sitting.
