What is cos -17Pi/12?

In a circle with the radius r, the horizontal axis x, and the vertical axis y, -17pi/12 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 -17pi/12.

Note that you can locate many terms including the cosine-17pi/12 value using the search form. On mobile devices you can find it by scrolling down. Enter, for instance, value of cos-17pi/12.
