| Name Ananya Puri Class 10th C Roll no. 02 | Maths activity Flashcards on chapter "Trignomatery" |
| Trignomatery | The word trignomatery is derived form the Greek words "tri" (meaning three) "gon" (Meaning side) "metron" (Meaning measure) |
| The Trignometric ratio | Sin 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 |
| Trignometric ratios of Complementary angles | Sin(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 |
| Trigonomateric identity | Cos2 θ + Sin2 θ = 1. 1 + Tan2 θ = Sec2 θ 1 + Cot2 θ = Cosec2 θ |
