Trig Identities Quiz (20+ Q&A) – MATH 2026 – Reciprocal, Cofunction, Pythagorean, and Quotient Identities

This concise quiz document for MATH 2026 includes over 20 fully answered questions on the foundational trigonometric identities used in right triangle trigonometry and algebraic verification. It covers sine, cosine, tangent, and their reciprocal identities (cosecant, secant, cotangent), cofunction relationships (like sin(90° − θ) = cos θ), Pythagorean identities, and quotient identities. Students are prompted to recall and apply identity definitions, such as sin θ = opp/hyp, csc θ = 1/sin θ, and tan θ = sin θ / cos θ, providing a compact but high-value review for verifying identities and simplifying expressions. This quiz is especially useful for mid-unit assessments or targeted review of trig identity formulas. Perfect for: Pre-Calculus or Advanced Math students studying trigonometry High school and early college learners reviewing trigonometric identities Test prep for ACT, SAT, or AP Pre-Calc exams Tutors and teachers needing a short-form identity reference quiz Keywords: trig identities, reciprocal identities, cofunction identities, Pythagorean identities, quotient identities, MATH 2026, sine cosine tangent, right triangle ratios, trig formulas, trigonometric quiz, simplify trig expressions, advanced math review
