WebThe three main functions in trigonometry are Sine, Cosine and Tangent. They are just the length of one side divided by another For a right triangle with an angle θ : For a given angle θ each ratio stays the same no … Move the mouse around to see how different angles (in radians or degrees) affect sine, cosine and tangent. In this animation the hypotenuse is 1, making the Unit Circle. Notice that the adjacent side and opposite side can be positive or negative, which makes the sine, cosine and tangent change between … See more Sine, Cosine and Tangent are the main functions used in Trigonometry and are based on a Right-Angled Triangle. Before getting stuck into the … See more Sine, Cosine and Tangent (often shortened to sin, cos and tan) are each a ratio of sidesof a right angled triangle: For a given angle θ each … See more Why are these functions important? 1. Because they let us work out angles when we know sides 2. And they let us work out sides when we know angles See more The triangle can be large or small and the ratio of sides stays the same.
