  2. Sine, Cosine and Tangent. Sine, 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

  3. Use cosine, sine and tan to calculate angles and sides of right-angled triangles in a range of contexts.

  4. Trigonometry involves three ratios - sine, cosine and tangent which are abbreviated to \(\sin\), \(\cos\) and \(\tan\). The three ratios can be found by calculating the ratio of two sides of a ...

  5. This page explains the sine, cosine, tangent ratio, gives on an overview of their range of values and provides practice problems on identifying the sides that are opposite and adjacent to a given angle. The Sine, Cosine and Tangent functions express the ratios of sides of a right triangle.

  6. What is sin cos tan? Sin cos tan is a shortened description of the three trigonometric functions of sine, cosine, and tangent. These functions associate the ratio of two sides of a right-angled triangle with an angle.

  7. 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.)

  8. The tangent of the angle = the length of the opposite side. the length of the adjacent side. So in shorthand notation: sin = o/h cos = a/h tan = o/a. Often remembered by: soh cah toa. Example. Find the length of side x in the diagram below: The angle is 60 degrees. We are given the hypotenuse and need to find the adjacent side.
