Edexcel IAL P3 | Solving Trigonometric Equations - Free CAST Revision Notes

Free Edexcel IAL P3 Trigonometric Equations Revision Notes

Build a reliable method for solving trigonometric equations with this free 11-page PDF from Study with Dr. Designed for students revising Edexcel International A-Level Pure Mathematics 3 (P3), the handout follows a clear sequence: reference angle, CAST quadrants, one-cycle solutions, then the full stated domain.

Topics covered

• Reference angles, principal values and the CAST diagram
• Sine, cosine and tangent solutions in radians and degrees
• Intervals wider than one cycle and tangent periodicity
• Multiple angles and shifted-angle domains
• Double-angle identities and reciprocal functions
• Quadratic trigonometric equations
• The connection between harmonic form and solving angles

Included: worked examples, quick checks, nine exam-style targeted practice questions, answers to the practice exercises and an exam checklist. The harmonic-form section explains the method rather than giving a fully worked numerical solution for a specific domain.

Format: downloadable PDF, 11 pages.

Price: free (£0).

Scope: focused P3 trigonometry revision, not a complete P3 revision pack. Answers are provided, not full worked solutions for every practice question.
