How To Remember The Trigonometric Table 9 Steps with Pictures

Three common trigonometric ratios are the sine sin cosine cos and tangent tan These are defined for acute angle A below adjacent opposite hypotenuse sin A opposite hypotenuse cos A adjacent hypotenuse tan A opposite adjacent A B C Sine, Cosine and Tangent The main functions in trigonometry are Sine, Cosine and Tangent They are simply one side of a right-angled triangle divided by another. For any angle " θ ": (Sine, Cosine and Tangent are often abbreviated to sin, cos and tan.) Example: What is the sine of 35°? Using this triangle (lengths are only to one decimal place):

Trigonometric RatiosSine, Cosine and Tangent (often shortened to sin, cos and tan) are each a ratio of sides of a right angled triangle: For a given angle θ each ratio stays the same no matter how big or small the triangle is To calculate them: Divide the length of one side by another side Example: What is the sine of 35°? In trigonometry there are six trigonometric ratios namely sine cosine tangent secant cosecant and cotangent These ratios are written as sin cos tan sec cosec or csc and cot in short Let us have a look at the right angled triangle shown below
