Cosine of 270
WebJan 24, 2024 · The values for Cos and Sin can be derived from each other as: Sin 0 = Cos 90. Sin 30 = Cos 60. Sin 45 = Cos 45. Sin 60 = Cos 30. Sin 90 = Cos 0 and so on. And using the values of Cos and Sin, you can find the value of Tan as: Tanθ = \ (\frac {Sin θ} {Cos θ}\) From the table below, you can check the values for Sin, Cos, Tan at different … WebThe ratios of the sides of a right triangle are called trigonometric ratios. Three common trigonometric ratios are the sine (sin), cosine (cos), and tangent (tan). These are defined for acute angle A A below: In these definitions, the terms opposite, adjacent, and hypotenuse refer to the lengths of the sides.
