FEUCAT Mathematics — TrigonometryConcept Map
Concept mapping is a retrieval-practice technique that works especially well on wide chapters like Trigonometry. When Far Eastern University writes a FEUCAT Mathematics item that mixes two sub-topics, a concept-mapped reviewer sees the intersection in seconds. This page provides that map for Trigonometry.
Exam context
For the Far Eastern University College Admission Test, Far Eastern University tests Mathematics under a "Core section" label, with Trigonometry in the 7th slot across 9 chapters. FEUCAT candidates must clear the Competitive overall score cut on the 2026 paper, which draws about a meaningful share of Mathematics questions. Date to watch: Q3–Q4 2026.
