Web2. Label a right triangle with one acute angle A. Since tan A = 15 8 you can label the opposite side with length 15 and the adjacent side with length 8. Then the hypotenuse has length 17 so that sin A = 15 17 and cos A = 8 17. For B, use sin 2 B + cos 2 B = 1. Since B is obtuse, its cosine is negative. tokyo fm school of lockWebThe tan (a + b) formula is used to express the tan compound angle formula in terms of tangent of individual angles.
