For the cosine that 30 levels we use the abbreviation *cos* because that the trigonometric function together with the level symbol °, and also write it together cos 30°.

You are watching: What is the cosine of 30 degrees

If you have been trying to find *what is cos 30°*, or if you have actually been wondering about cos 30 degrees in radians, then you are appropriate here, too.

In this post you can find the cos 30° value, together with identities.

Read ~ above to find out all around the cos of 30°.

## Cos 30 Degrees

If you want to recognize *what is cos 30 degrees* in terms of trigonometry, then navigate directly to the explanations in the next paragraph; what’s ahead in this section is the worth of cos 30°:

cos30° = √(3)/2cos 30° = √(3)/2cos 30 levels = √(3)/2" onclick="if (!window.__cfRLUnblockHandlers) return false; return fbs_click()" target="_blank" rel="nofollow noopener noreferrer" data-cf-modified-0d2ef3d667f7c36bd0478f98-="">

The cos the 30 degrees is √(3)/2, the exact same as cos of 30 levels in radians. To achieve 30 degrees in radian main point 30° by $\pi$ / 180° = 1/6 $\pi$. Cos 30degrees = cos (1/6 × $\pi)$.

Our results of cos30° have been rounded to five decimal places. If you want cosine 30° with higher accuracy, then use the calculator below; our tool display screens ten decimal places.

To calculation cos 30 levels insert the edge 30 in the ar labelled °, however if you want to calculate cos 30 in radians, climate you need to press the swap unit button first.

### Calculate cos

A yes, really Cool Cosine Calculator and Useful Information! you re welcome ReTweet. Click come TweetBesides cos30°, comparable trigonometric calculations ~ above our site include, but are not limited, to:

The identities that cosine 30° space as follows:cos30°= sin (90°+30°) = sin 120°= sin (90°-30°) = sin 60°

-cos30°= cos (180°+30°) = cos 210°= cos (180°-30°) = cos 150°Note that cos30° is periodic: cos (30° + *n* × 360°) = cos 30 degrees, n$\hspace5px \in \hspace5px \mathbbZ$.

There are an ext formulas because that the double angle (2 × 30°), half angle ((30/2)°) and also the sum, difference and also products of two angles such as 30° and β.

You have the right to locate all of them in the respective short article found in the header menu. To discover everything about cos -30° click the link. And also here is all about sin 30°, including, because that instance, a converter.

In terms of the other 5 trigonometric functions, cos that 30° =

$\pm \sqrt1-\sin^2 30 ^\circ$ $\pm\frac1\sqrt1 + \tan^2 30^\circ$ $\pm\frac\cot 30^\circ\sqrt1 + \cot^2 30^\circ$ $\frac1\sec 30^\circ$ $\pm\frac\sqrt\csc^2 30^\circ – 1 \csc 30^\circ$As the cosine role is the reciprocal of the secant function, 1 / sec 30° = cos30°.

In the next part we discuss the trigonometric definition of cos30°, and there girlfriend can additionally learn what the search calculations type in the sidebar is used for.

## What is cos 30°?

In a triangle which has one angle of 90 degrees, the cosine of the angle of 30° is the ratio of the length of the adjacent side *a* to the size of the hypotenuse *h*: cos 30° = a/h.

In a circle v the radius r, the horizontal axis x, and the vertical axis y, 30 degrees is the angle developed by the two sides x and r; r relocating counterclockwise is the optimistic angle.

As thorough in the unit-circle definition on our homepage, suspect r = 1, in the intersection of the point (x,y) and also the circle, x = cos 30°.

Bringing together the triangle meaning and the unit circle an interpretation of cosine 30 degrees, a = x and h = r = 1. It follows that $x\hspace5px =\hspace5px\fracadjacenthypotenuse\hspace5px=\hspace5px\cos 30^\circ$.

Note the you can locate plenty of terms including the cosine30° value making use of the search form. Top top mobile gadgets you can discover it by scrolling down. Enter, for instance, worth of cos30°.

Along the same lines, utilizing the previously mentioned form, have the right to you look up terms such together cos 30° value, cos 30, cos30° value and *what is the cos of 30 degrees*, just to surname a few.

Given the periodic property that cosine the 30°, to recognize the cosine of an angle > 360°, e.g. 750°, calculation cos 750° together cos (750 mod 360)° = cosine the 30°, or look it up v our form.

## Conclusion

The typically asked concerns in the context incorporate *what is cos 30 degrees* and *what is the cos that 30 degrees* because that example; analysis our contents they space no-brainers.

But, if there is something else about cosine 30° friend would prefer to know, fill in the form on the bottom of this post, or send us an e-mail with a subject line such together cosine 30 degrees.
