Build diagnostic and summative assessments on trigonometric equations for your senior maths students. See exactly how well they can solve equations involving sine, cosine and tangent, apply identities, and reason through multi-step problems — then act on the data lesson by lesson.

Diagnostic Assessment


Printable Summative Assessments
Problem Solving and Scaffolded Questions

A short diagnostic that shows where each student sits with trigonometric equations before you start the unit. Students answer a focused set of questions covering basic equations, identities and inverse functions; you get a per-student and per-class view of who has the prerequisites and who still needs work on the underlying skills.
Print-ready summative papers that mirror the structure of typical end-of-unit and external exam questions on trigonometric equations. Use them as a unit test, a mock exam or a take-home practice paper. Answer keys and worked solutions are included so marking is fast.
Each assessment scaffolds from single-step equations through to multi-step problems that combine identities, multiple angles and applied contexts. Students are pushed to show their reasoning, which makes it easier to see whether errors come from algebra, trig knowledge or exam technique.

Practical Applications
Students solve equations involving sine, cosine and tangent across the standard domains, including questions that ask for solutions in degrees and radians. Items progress from one-step equations through to those that require factorising, using inverse functions or working with multiple angles. The assessment surfaces whether errors are due to algebra, unit-circle recall or domain restrictions.
Students apply the Pythagorean, double-angle and reciprocal identities to simplify expressions and solve more complex equations. Questions are designed to test whether students can choose the right identity for the situation, not just recall the formula sheet, which is one of the strongest predictors of exam performance in trigonometry.
Students work through applied questions that use trigonometric equations to model real situations — wave behaviour, oscillation, periodic motion and angle-of-elevation problems. These items help students see why solving trig equations matters beyond the test, and give you a clear read on which students can transfer the skill into context.
