Trigonometriy 삼각법 빗변, 대변, 인접변 Hypotenuse 빗변 Opposite 대변 Adjacent 인접변 sin(sine) Θ = Opposite / Hypotenuse (SOH) cos(cosine) Θ = Adjacent / Hypotenuse (CAH) tan(tangent) Θ = Opposite / Adjacent (TOA) 암기법 SOH CAH TOA Pythagorean trig identity 삼각함수 제곱공식 Sin & cos of complementary angles 여각의 sin & cos 역삼각비 Reciprocal trig ratios sin(sine) Θ = Opposite / Hypotenuse (SOH) → csc(cosecant) Θ = Hypotenuse..
