WebNov 19, 2024 · tan A = (sin A) / (cos A) You’ll use the tangent ( tan) function a lot more than the last three functions. (I’ll get to them in a minute.) There’s an alternative way to remember the meaning of the tangent . Remember from the diagram that sin A = opposite/hypotenuse and cos A = adjacent/hypotenuse. WebThe six trigonometric functions are sine, cosine, secant, cosecant, tangent and cotangent. By using a right-angled triangle as a reference, the trigonometric functions and identities are derived: sin θ = Opposite Side/Hypotenuse. cos θ = Adjacent Side/Hypotenuse. tan θ = Opposite Side/Adjacent Side. nascar races in michigan
