Tangent of angle formula

WebTan(a-b) identity is one of the trigonometry identities for compound angles. It is applied when the angle for which the value of the tangent function is to be calculated is given in the form of the difference of any two angles.The angle (a-b) in the formula of tan(a-b) represents the compound angle. 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 functions, it helps to give a nameto each side of a right triangle: 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 … 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 angle and point "B" to change the size: Good … See more
