In trigonometry, the three primary ratios are sine, cosine and tangent. Tan(45∘) = 1 sin(45∘) = √2 2 cos(45∘) = √2 2 here are some other special angles :) answer link Sep 13, 2015 consider the idea that a triangle will always have an angle sum of 180o. The value of cos 45° is equal to 1/√2. Web cos(45∘) = √2 2 explanation: You may have seen that trigonometric functions are used directly on a triangles only when you have a right triangle. If the trigonometric ratio of any angle is taken for a right angled triangle, then the values depend on. 45∘ is a special angle, along with 30∘, 60∘, 90∘, 180∘, 270∘, 360∘. Cos 45° = cos π/4 = 1/√2. Web the subsequent values, cos (30°), cos (45°), cos (60°), and cos (90°) follow a pattern such that, using the value of cos (0°) as a reference, to find the values of cosine for the subsequent angles, we simply decrease the number under the radical sign in the numerator by 1, as shown below:
