Cos of 2pi/3

Can somebody help me?

.

We must now determine the reference angle for degrees. Since degrees is in quadrant II, the reference angle is found by using the expression - theta , where theta is the angle in degrees. Calculating we get a reference angle of 60 degrees. We must now apply our knowledge of the special triangles to continue. The special triangle that contains 60 degrees is the degrees, that has side lengths of 1, sqrt 3 and 2 , respectively. So, the hypotenuse measures 2, the side opposite our angle measures sqrt 3 and the side adjacent measures 1. For example, we can say with this acronym that cos is positive in quadrant IV. Feel free to ask anything more either on my Socratic dashboard or on the main questions page. I understand that this might at first seem like a long and complicated process.

Cos 2pi gives the value of the cosine function when the angle made with the positive x-axis is 2pi, that is, one complete rotation. The value of cos 2pi is one such value and can be found using different methods. In this article, we will determine the value of cos 2pi as 1 using various methods along with some examples. So, the value of cos 2pi is equal to the value of cos 0 which is 1. So, cos 2pi is equal to 1. Now, we will use some of these values to determine the value of cos 2pi using different methods such as graphically, standard angles, unit circle, and double angle formula. Given below is the graph of cos x. We know that the period of cos x is 2pi and the graph repeats after every 2pi radians.

  1. It is very a pity to me, that I can help nothing to you. But it is assured, that you will find the correct decision.

  2. I apologise, but, in my opinion, you are not right. I can prove it. Write to me in PM.
