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:
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.
Our results of cos17pi/12 have been rounded to five decimal places. If you want cosine 17pi/12 with higher accuracy, then use the calculator below; our tool displays ten decimal places.
To calculate cos 17pi/12 radians insert the angle 17pi/12 in decimal notation, but if you want to calculate cos 17pi/12 in degrees, then you have to press the swap unit button first.
Calculate cos [radians]
The identities of cosine 17pi/12 are as follows:
= sin (pi/2 + 17pi/12) = sin 23/12 pi
= sin (pi/2 – 17pi/12) = sin -11/12 pi
-cos17pi/12
= cos (pi + 17pi/12) = cos 29/12 pi
= cos (pi – 17pi/12) = cos -5/12 pi
There are more formulas for the double angle (2 × 17pi/12), half angle ((17pi/12/2)) as well as the sum, difference and products of two angles such as 17pi/12 and β.

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 cosine17pi/12 value using the search form. On mobile devices you can find it by scrolling down. Enter, for instance, value of cos17pi/12.
Along the same lines, using the aforementioned form, can you look up terms such as cos 17pi/12 value, cos 17pi/12, cos17pi/12 value and what is the cos of 17pi/12 radians, just to name a few.
Given the periodic property of cosine of 17pi/12, to determine the cosine of an angle > 2pi, e.g. 65/12 pi, calculate cos 65/12 pi as cos (65/12 pi mod 2pi) = cosine of 17pi/12, or look it up with our form.
