Flashcards on chapter "Trignomatery"
2TrignomateryThe word trignomatery is derived form the Greek words "tri" (meaning three) "gon" (Meaning side) "metron" (Meaning measure)
3The Trignometric ratioSin A = P/H
Cos A = B/H
Tan A = P/B
Cosec A = H/P
Sec A = H/B
Cot A = B/P
B-Base
P- perpendicular
H-hypotenuse
4Trignometric ratios of Complementary anglesSin(90-A) = Cos A
Tan(90-A) = Cot A
Sec(90-A) = Cosec A
Cos(90-A) = sin A
Cot(90-A) = tan A
Cosec(90-A) = sec A
5Trigonomateric identityCos2 θ + Sin2 θ = 1.
1 + Tan2 θ = Sec2 θ
1 + Cot2 θ = Cosec2 θ
