Since the angle 135° 135 ° is in the second quadrant, subtract 135° 135 ° from 180° 180 °. 180°− 135° 180 ° - 135 °.Find the value of cos 75 °. Hence, the value of cos 75 ° is 3 - 1 2 2.For memorising cos 0°, cos 30°, cos 45°, cos 60° and cos 90°. Cos is the opposite of sin. We should learn it like. cos 0° = sin 90° = 1. cos 30° = sin 60° = √3/2. cos 45° = sin 45° = 1/√2. cos 60° = sin 30° = 1/2. cos 90° = sin 0° = 0. So, for cos, it will be like.Beware - the notation cos-1 have two very different meanings: cos-1 (x) = 1/cos (x), i.e., the multiplicative inverse of cos (x); or. cos-1 (x) = arccos (x), i.e., the inverse function of the cosine. In other words, we have the problem of determining the angle whose cosine equals x. We assume that you have in mind …Using the half angle formula: cos 2 ( x) = 1 2 ( 1 + cos ( 2 x)) Using your angle x = 22.5 ∘ and 2 x = 45 ∘ you get. cos 2 ( 22.5 ∘) = 1 2 ( 1 + cos ( 45 ∘)) But cos ( 45 ∘) = 2 2. ∴ cos 2 ( 22.5 ∘) = 2 + 2 4. cos ( 22.5 ∘) = 2 + 2 4 ≈ 0.9238.Trigonometry.
