For the station trigonometric role of sine 1/2 we typically employ the abbreviation arcsin and write it together arcsin 1/2 or arcsin(1/2).
You are watching: Arcsin (-1/2)
If you have actually been in search of what is arcsin 1/2, either in degrees or radians, or if you have been wondering about the station of sin 1/2, then you are ideal here, too.
In this write-up you can find the angle arcsine the 1/2, along with identities.
Read on to discover all around the arcsin the 1/2.
Arcsin the 1/2
If you desire to recognize what is arcsin 1/2 in terms of trigonometry, check out the explanations in the critical paragraph; ahead in this ar is the value of arcsine(1/2):
arcsin 1/2 = π/6 rad = 30°arcsine 1/2 = π/6 rad = 30 °arcsine that 1/2 = π/6 radians = 30 degrees" onclick="if (!window.__cfRLUnblockHandlers) return false; return fbs_click()" target="_blank" rel="nofollow noopener noreferrer" data-cf-modified-d7341c2456032ab957b548ee-="">
The arcsin the 1/2 is π/6 radians, and also the value in levels is 30°. To adjust the result from the unit radian come the unit level multiply the edge by 180° / $\pi$ and obtain 30°.
Our results over contain fountain of π for the results in radian, and also are precise values otherwise. If girlfriend compute arcsin(1/2), and any other angle, utilizing the calculator below, then the value will be rounded come ten decimal places.
To attain the edge in degrees insert 1/2 together decimal in the field labelled “x”. However, if you want to be provided the edge opposite to 1/2 in radians, then you have to press the swap units button.

The identities the arcsine 1/2 room as follows: arcsin(1/2) =$\frac\pi2$ – arcscos(1/2) ⇔ 90°- arcscos(1/2) -arcsin(-1/2) arccsc(1/1/2) $\fracarccos(1-2(1/2)^2)2$ $2 arctan(\frac1/21 + \sqrt1 – (1/2)^2)$
The infinite series of arcsin 1/2 is: $\sum_n=0^\infty \frac(2n)!2^2n(n!)^2(2n+1)(1/2)^2n+1$.
Next, we comment on the derivative the arcsin x for x = 1/2. In the complying with paragraph girlfriend can furthermore learn what the search calculations kind in the sidebar is supplied for.
Derivative that arcsin 1/2
The derivative the arcsin 1/2 is particularly useful to calculation the train station sine 1/2 together an integral.
The formula because that x is (arcsin x)’ = $\frac1\sqrt1-x^2$, x ≠ -1,1, so for x = 1/2 the derivative amounts to 1.1547005384.
Using the arcsin 1/2 derivative, we have the right to calculate the angle as a definite integral:
arcsin 1/2 = $\int_0^1/2\frac1\sqrt1-z^2dz$.
The connection of arcsin the 1/2 and also the trigonometric attributes sin, cos and tan is:sin(arcsine(1/2)) = 1/2 cos(arcsine(1/2)) = $\sqrt1 – (1/2)^2$ tan(arcsine(1/2)) = $\frac1/2\sqrt1 – (1/2)^2$
Note that you have the right to locate many terms including the arcsine(1/2) value using the find form. On mobile tools you can discover it through scrolling down. Enter, because that instance, arcsin1/2 angle.
Using the aforementioned form in the same way, friend can also look increase terms consisting of derivative of train station sine 1/2, station sine 1/2, and also derivative that arcsin 1/2, just to surname a few.
In the next component of this write-up we discuss the trigonometric meaning of arcsine 1/2, and there we likewise explain the difference in between the inverse and the reciprocal of sin 1/2.
What is arcsin 1/2?
In a triangle which has one edge of 90 degrees, the sine the the angle α is the ratio of the size of the opposite side o to the size of the hypotenuse h: sin α = o/h.
In a circle through the radius r, the horizontal axis x, and the vertical axis y, α is the angle created by the 2 sides x and also r; r relocating counterclockwise specifies the hopeful angle.
As adheres to from the unit-circle definition on our homepage, assumed r = 1, in the intersection that the suggest (x,y) and also the circle, y = sin α = 1/2 / r = 1/2. The angle whose sine value amounts to 1/2 is α.
In the term <-π/2, π/2> or <-90°, 90°>, over there is only one α who sine value equates to 1/2. For that interval we define the function which determines the worth of α as y = arcsin(1/2)." onclick="if (!window.__cfRLUnblockHandlers) return false; return fbs_click()" target="_blank" rel="nofollow noopener noreferrer" data-cf-modified-d7341c2456032ab957b548ee-="">
From the an interpretation of arcsin(1/2) complies with that the inverse role y-1 = sin(y) = 1/2. Observe the the reciprocal duty of sin(y),(sin(y))-1 is 1/sin(y).
Avoid misconceptions and remember (sin(y))-1 = 1/sin(y) ≠ sin-1(y) = arcsin(1/2). And make sure to know that the trigonometric duty y=arcsine(x) is identified on a restricted domain, where it evaluate to a single value only, referred to as the principal value:
In order to it is in injective, additionally known as one-to-one function, y = arcsine(x) if and only if sin y = x and also -π/2 ≤ y ≤ π/2. The domain the x is −1 ≤ x ≤ 1.
The typically asked inquiries in the context encompass what is arcsin 1/2 degrees and also what is the station sine 1/2 for example; analysis our content they are no-brainers.
But, if there is other else around the topic friend would prefer to know, to fill in the type on the bottom of this post, or send us an e-mail with a subject line such as arcsine 1/2 in radians.
