## What is cos 11Pi/6?

In a circle with the radius r, the horizontal axis x, and the vertical axis y, 11pi/6 is the angle formed by the two sides x and r; r moving counterclockwise is the positive angle.

As detailed in the unit-circle definition on our homepage, assumed r = 1, in the intersection of the point (x,y) and the circle, x = cos 11pi/6.

Note that you can locate many terms including the cosine11pi/6 value using the search form. On mobile devices you can find it by scrolling down. Enter, for instance, value of cos11pi/6.

Along the same lines, using the aforementioned form, can you look up terms such as cos 11pi/6 value, cos 11pi/6, cos11pi/6 value and what is the cos of 11pi/6 radians, just to name a few.

Given the periodic property of cosine of 11pi/6, to determine the cosine of an angle > 2pi, e.g. 35/6 pi, calculate cos 35/6 pi as cos (35/6 pi mod 2pi) = cosine of 11pi/6, or look it up with our form.
