Solution. We want to find tan (22 1 2 ). we know (22 1 2) = 45 2. it is easy to guess that we will be using. trigonometric ratios of 45∘ to find tan 22 1 2 now we have to think of some formula which connects. tan 22 1 2 and tan 45. We know tan2A = 2tanA 1−tan2A. If A = 22 1 2 in this equation, we will get a quadratic in tan 22 1 2.

tan t = -b/2a +- d/2a = -2/1 + 2sqrt2/2 = - 1 +- sqrt2. Answer: tant = tan(22.5) = − 1 ± √2. Since tan 22.5 is positive, then take the positive answer: tan (22.5) = - 1 + sqrt2. Answer link. Find tan (22.5) Answer: -1 + sqrt2 Call tan (22.5) = tan t --> tan 2t = tan 45 = 1 Use trig identity: tan 2t = (2tan t)/ (1 - tan^2 t) (1) tan 2t = 1.

The law of tangents describes the relationship between the tangent of two angles of a triangle and the lengths of the opposite sides. Specifically, it states that: (a - b) / (a + b) = tan (0.5 (α - β)) / tan (0.5 (α + β)) Although the law of tangents is not as popular as the law of sines or the law of cosines, it may be useful when we have.

Trigonometry is a branch of mathematics concerned with relationships between angles and side lengths of triangles. In particular, the trigonometric functions relate the angles of a right triangle with ratios of its side lengths. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical.

To find the value of tan 22 degrees using the unit circle: Rotate 'r' anticlockwise to form 22° angle with the positive x-axis. The tan of 22 degrees equals the y-coordinate (0.3746) divided by x-coordinate (0.9272) of the point of intersection (0.9272, 0.3746) of unit circle and r. Hence the value of tan 22° = y/x = 0.404 (approx).
