Cos 60 or cos pi/3. In trigonometry, the cosine function is defined as the ratio of the adjacent side to the hypotenuse. The value of Cos 60 degree is 1/2 Another Different form of Cos 60° is cos pi/3 or cos π/3 Hence, cos pi/3 = 1/2. Geometrically Derivation of cosine 60.Either you mean "cos(x) multiplied by pi", (i.e pi*cos(x)) or "cos(pi)" (i.e cosine of pi), but it is unclear which you mean from the question. cos pi over four equals the square root of 2 over 2 This value can be found by looking at a unit circle.Question 73942This question is from textbook Algebra and Trigonomerty : Find the exact value of cos^-1 the possible answers are a. -PI/3 b. PI/3 c. 2PI/3 d. 4PI/3 However, since the range of inverse cosine is [0, ], we need to find a co-angle that is in the interval [0, ] (in other words we need to reduce .Simple and best practice solution for Cos(-pi/3) equation. Check how easy it is, and learn it for the future. Our solution is simple, and easy to understand, so don`t hesitate to use it as a solution of your homework. If it's not what You are looking for type in the equation solver your own equation and let us...pi/3 radians = 60 degrees, and cos is looking for the side adjacent to the 60 degree angle. in a 30-60-90 triangle, the sides are in the ratio 1-sqrt(3)-2.

Summary :
