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 positive and … 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 ratio stays the same no matter how big or small the triangle is To calculate them: Divide … 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. Only the angle changes the ratio. Try dragging point "A" to change the … See more WebNow as per sine, cosine and tangent formulas, we have here: Sine θ = Opposite side/Hypotenuse = BC/AC Cos θ = Adjacent side/Hypotenuse = AB/AC Tan θ = Opposite side/Adjacent side = BC/AB We can see clearly …
