For the cos minus 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 Minus 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 cos-23pi/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 -17/12 pi

= sin (pi/2 + 23pi/12) = sin 29/12 pi

-cos-23pi/12

= cos (pi – 23pi/12) = cos -11/12 pi

= cos (pi + 23pi/12) = cos 35/12 pi

*n*× 2pi) = cos -23pi/12, n$\hspace{5px} \in \hspace{5px} \mathbb{Z}$.

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 cosine-23pi/12 value using the search form. On mobile devices you can find it by scrolling down. Enter, for instance, value of cos-23pi/12.

Along the same lines, using the aforementioned form, can you look up terms such as cos -23pi/12 value, cos -23pi/12, cos-23pi/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.
