WebAs suggested by Jonas: 1) Draw a right triangle and label one of the (non 90 ∘) angles α. 2) You know that the tangent of α is 1 2. Since tan = opposite adjacent, you can label the side of the triangle adjacent to α "1" and the opposite side "2". 3) By the Pythagorean theorem, you can find the length of the hypotenuse of the triangle. 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.
