For the train station trigonometric duty of cosine 1/2 we generally employ the abbreviation arccos and also write it together arccos 1/2 or arccos(1/2).

If you have actually been in search of what is arccos 1/2, either in levels or radians, or if you have been wondering around the train station of cos 1/2, climate you are right here, too.

In this short article you can uncover the angle arccosine of 1/2, in addition to identities.

Read on to learn all about the arccos the 1/2.

Arccos of 1/2

If you want to recognize what is arccos 1/2 in terms of trigonometry, examine out the explanations in the last paragraph; front in this ar is the worth of arccosine(1/2):

arccos 1/2 = π/3 rad = 60°arccosine 1/2 = π/3 rad = 60 °arccosine the 1/2 = π/3 radians = 60 degrees" onclick="if (!window.__cfRLUnblockHandlers) return false; return fbs_click()" target="_blank" rel="nofollow noopener noreferrer" data-cf-modified-9fb97b89e3d71f3fe40f4d93-="">Share ~ above Facebook

The arccos that 1/2 is π/3 radians, and also the worth in degrees is 60°. To change the result from the unit radian to the unit level multiply the edge by 180° / $pi$ and obtain 60°.

Our results over contain fountain of π because that the results in radian, and are precise values otherwise. If you compute arccos(1/2), and also any other angle, utilizing the calculator below, then the worth will it is in rounded to ten decimal places.

To attain the edge in levels insert 1/2 together decimal in the ar labelled “x”. However, if you want to be given the angle nearby to 1/2 in radians, then you should press the swap units button.

The identities the arccosine 1/2 room as follows: arccos(1/2) =

$fracpi2$ – arcsin(1/2) ⇔ 90°- arcsin(1/2) $pi$ – arccos(-1/2) ⇔ 180° – arcos(-1/2) arcsec(1/1/2) $arcsin(sqrt1-(1/2)^2)$ $2arctan(fracsqrt1-(1/2)^21+(1/2))$

The infinite collection of arccos 1/2 is: $fracpi2$ – $sum_n=0^infty frac(2n)!2^2n(n!)^2(2n+1)(1/2)^2n+1$.

Next, we talk about the derivative the arccos x for x = 1/2. In the adhering to paragraph you can in addition learn what the search calculations kind in the sidebar is offered for.

Derivative the arccos 1/2

The derivative that arccos 1/2 is particularly useful to calculate the train station cosine 1/2 as an integral.

The formula for x is (arccos x)’ = – $frac1sqrt1-x^2$, x ≠ -1,1, so for x = 1/2 the derivative amounts to -1.1547005384.

Using the arccos 1/2 derivative, we can calculate the angle as a identify integral:

arccos 1/2 = $int_1/2^1frac1sqrt1-z^2dz$.

The partnership of arccos the 1/2 and also the trigonometric functions sin, cos and also tan is:

sin(arccosine(1/2)) =$sqrt1-(1/2)^2$ cos(arccosine(1/2)) = 1/2 tan(arccosine(1/2)) = $fracsqrt1-(1/2)^21/2$

Note the you deserve to locate many terms consisting of the arccosine(1/2) value using the search form. Top top mobile devices you can uncover it by scrolling down. Enter, because that instance, arccos1/2 angle.

Using the aforementioned type in the same way, friend can additionally look up terms consisting of derivative of train station cosine 1/2, station cosine 1/2, and also derivative the arccos 1/2, simply to surname a few.

In the next component of this write-up we discuss the trigonometric meaning of arccosine 1/2, and also there we also explain the difference between the inverse and also the reciprocal of cos 1/2.

What is arccos 1/2?

In a triangle which has actually one edge of 90 degrees, the cosine that the angle α is the ratio of the length of the nearby side a to the size of the hypotenuse h: cos α = a/h.

In a circle v the radius r, the horizontal axis x, and also the vertical axis y, α is the angle created by the 2 sides x and also r; r moving counterclockwise defines the positive angle.

As complies with from the unit-circle definition on ours homepage, presume r = 1, in the intersection that the allude (x,y) and also the circle, x = cos α = 1/2 / r = 1/2. The angle whose cosine value equals 1/2 is α.

In the interval <0, π> or <0°, 180°>, over there is only one α who arccosine value equals 1/2. For the interval we specify the function which determines the value of α as y = arccos(1/2)." onclick="if (!window.__cfRLUnblockHandlers) return false; return fbs_click()" target="_blank" rel="nofollow noopener noreferrer" data-cf-modified-9fb97b89e3d71f3fe40f4d93-="">Share top top Facebook

From the definition of arccos(1/2) follows that the inverse duty y-1 = cos(y) = 1/2. Observe that the reciprocal function of cos(y),(cos(y))-1 is 1/cos(y).

Avoid misconceptions and also remember (cos(y))-1 = 1/cos(y) ≠ cos-1(y) = arccos(1/2). And also make sure to recognize that the trigonometric role y=arccos(x) is defined on a minimal domain, wherein it evaluates to a solitary value only, referred to as the major value:

In order to it is in injective, likewise known together one-to-one function, y = arccos(x) if and only if cos y = x and 0 ≤ y ≤ π. The domain that x is −1 ≤ x ≤ 1.

Conclusion

The commonly asked questions in the context include what is arccos 1/2 degrees and what is the train station cosine 1/2 because that example; analysis our content they space no-brainers.

But, if there is something else about the topic you would favor to know, fill in the type on the bottom that this post, or send us an email with a topic line such as arccosine 1/2 in radians.
