For the cosine of 23pi/12 we use the abbreviation cos for the trigonometric function and write it as cos 23pi/12.
If you have been looking for what is cos 23pi/12, or if you have been wondering about cos 23pi/12 radians in degrees, then you are right here, too.
In this post you can find the cos 23pi/12 value, along with identities.
Read on to learn all about the cos of 23pi/12.
Cos 23Pi/12 Radians
If you want to know what is cos 23pi/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 23pi/12:
cos 23pi/12 = (√6+√2)/4
cos 23pi/12 radians = (√6+√2)/4
The cos of 23pi/12 radians is (√6+√2)/4, the same as cos of 23pi/12 radians in degrees. To change 23pi/12 radians to degrees multiply 23pi/12 by by 180° / $\pi$ = 345°. Cos 23pi/12 = cos 345 degrees.
Our results of cos23pi/12 have been rounded to five decimal places. If you want cosine 23pi/12 with higher accuracy, then use the calculator below; our tool displays ten decimal places.
To calculate cos 23pi/12 radians insert the angle 23pi/12 in decimal notation, but if you want to calculate cos 23pi/12 in degrees, then you have to press the swap unit button first.
Calculate cos [radians]
The identities of cosine 23pi/12 are as follows:
= sin (pi/2 + 23pi/12) = sin 29/12 pi
= sin (pi/2 – 23pi/12) = sin -17/12 pi
-cos23pi/12
= cos (pi + 23pi/12) = cos 35/12 pi
= cos (pi – 23pi/12) = cos -11/12 pi
There are more formulas for the double angle (2 × 23pi/12), half angle ((23pi/12/2)) as well as the sum, difference and products of two angles such as 23pi/12 and β.

What is cos 23Pi/12?
In a circle with the radius r, the horizontal axis x, and the vertical axis y, 23pi/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 23pi/12.
Note that you can locate many terms including the cosine23pi/12 value using the search form. On mobile devices you can find it by scrolling down. Enter, for instance, value of cos23pi/12.
Along the same lines, using the aforementioned form, can you look up terms such as cos 23pi/12 value, cos 23pi/12, cos23pi/12 value and what is the cos of 23pi/12 radians, just to name a few.
Given the periodic property of cosine of 23pi/12, to determine the cosine of an angle > 2pi, e.g. 71/12 pi, calculate cos 71/12 pi as cos (71/12 pi mod 2pi) = cosine of 23pi/12, or look it up with our form.
