Use our arcsin calculator to find the inverse trigonometric function arcsin(x) in degrees or radians. Domain of arcsin x for real result. Range of usual principal values. arcsin(x) sin-1x, asin.The domain of the function $\arcsin x$ is the interval $[-1,1]$; it isn't defined for any value of $x$ outside that interval.Therefore, #sin(arcsin x+arccos x)=sin(pi/2)=1#. Case with non-positive #x# we will consider Now we can calculate the value of the original expression: #sin(arcsin x+arccos x) =# #= sin(arcsin x)...

Second, the reason that arcsin (sin x) shows corners is that arcsin (sin x) is not in general equal to x. Since for each y∈[-1, 1] there are many x such that sin x = y, it is not possible to define a true inverse...Evaluating sin(arcsin x), etc. 9 205 просмотров9,2 тыс. просмотров.

In trigonometry, The arcsin function represents the inverse of the sine function. Its purpose is to returns the angle whose sine is a given $$ sin-1x = arcsin x$$. It means that the arc whose sine is x.The arcsine is one of the inverse trigonometric functions (antitrigonometric functions) and is the inverse of the sine function. It is sometimes written as sin-1(x), but this notation should be avoided as it can......x, the function y = arcsin(x) is defined so that sin(y) = x. For a given real number x, with −1 ≤ x ≤ 1 With this restriction, for each x in the domain, the expression arcsin(x) will evaluate only to a single...Strictly speaking, the symbol sin-1( ) or Arcsin( ) is used for the Arcsine function, the function that undoes the sine. This function returns only one answer for each input and it corresponds to the blue...
Actually, my remark above is a bit vague. I shall make it extra actual here.
The motivation is clear. We wish to invert the function $\sin:\Bbb R\to \Bbb R$. But this function isn't injective, neither is it surjective, and that is a problem, since a function is invertible if and most effective if it is bijective.
So if we need to invert $\sin$, we first have to limit its area and codomain appropriately to make it bijective. The restriction $\sin:[-\frac\pi2,\frac\pi2]\to[-1,1]$ is a bijective function, so it has an inverse. (Stricly talking, this is a new function, however we most often use the same name for it, which might add to the confusion.) And it's the inverse of this serve as that is known as $\arcsin:[-1,1]\to [-\frac\pi2,\frac\pi2]$. That's why $\arcsin$ is outlined only on the period $[-1,1]$ and the functions $\sin:[-\frac\pi2,\frac\pi2]\to[-1,1]$ and $\arcsin:[-1,1]\to [-\frac\pi2,\frac\pi2]$ are inverse to one another.
Now, we can nonetheless take a look at what happens if we take the unique function $\sin:\Bbb R\to\Bbb R$ and compose it with $\arcsin:[-1,1]\to [-\frac\pi2,\frac\pi2]$, but then the functions are not inverse anymore and we get the behaviour you describe above.
