What is the solution to arccos 0.5 express answer in radians

arccos (0.5) is

Step-by-step explanation:

With the arccos(0.5)  in this problem, you are asked which angle renders its cosine equal to 0.5 (or 1/2).

Recall that there are special angles in the unitary circle that render well know values like 1/2. There are two angle values between 0 and the full circle ( radians), that render cosine function equal 1/2, and they are: , and .

The arccos uses just the first one as answer over the restricted domain between 0 and , since otherwise it will not be considered a function.

So the answer is that the arccos (0.5) is
