Welcome to cos 17pi/12, our post aboutthe cosine of 17pi/12.

For the cosine of 17pi/12 we use the abbreviation cos for the trigonometric function and write it as cos 17pi/12.

If you have been looking for what is cos 17pi/12, or if you have been wondering about cos 17pi/12 radians in degrees, then you are right here, too.

In this post you can find the cos 17pi/12 value, along with identities.

Read on to learn all about the cos of 17pi/12.

## Cos 17Pi/12 Radians

If you want to know what is cos 17pi/12 radians in terms of trigonometry, then navigate straight to the explanations in the next paragraph; what’s ahead in this section is the value of cos 17pi/12:

cos17pi/12 = -(√6-√2)/4
cos 17pi/12 = -(√6-√2)/4
cos 17pi/12 radians = -(√6-√2)/4

The cos of 17pi/12 radians is -(√6-√2)/4, the same as cos of 17pi/12 radians in degrees. To change 17pi/12 radians to degrees multiply 17pi/12 by by 180° / $\pi$ = 255°. Cos 17pi/12 = cos 255 degrees.

## 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.
