TRIGONOMETRY Trigonometry is the study of angle measurement and functions that depends on angle. The fundamental trigonometric ratios are Sine (sin) Cosine (Cos) Tangent (Tan) Others are cosecant (cosec) Secant (sec) Cotangent (cot ) Let θ be the angle in a right angled triangle; then we say Sin θ COS θ Tan θ And = … Read more
