Nov 21, 2023 · Learn to define what an arcsin function is. Discover the inverse trigonometric functions. Learn how to find the inverse of the sine function. See...

Aug 9, 2022 · Take the sine of both sides, and use the angle addition formula, then further simplify it by using the fact that $\cos\arcsin t=\sqrt {\cos^2\arcsin t}=\sqrt {1-\sin^2\arcsin t}=\sqrt {1-t^2}$.

Dec 4, 2018 · I first learned that arcsin and inverse sine are two ways of saying the same thing. But then I was thinking about the inverse sine function being a function, so it must be limited in …

Nov 27, 2017 · You'd better say that "their effects cancel out" or compensate each other. $\arcsin (\sin x)=x$, so that the composition of the two functions is neutral (at least in some range).

Dec 5, 2018 · Sorry for asking such question. I have a very basic understanding of $\\arcsin, \\arccos, \\arctan$ functions. I do know how their graph looks like and not much more beyond …

Jun 16, 2013 · 1 $\arcsin $ is defined to be the inverse of $\sin$ but restricted to a certain range.

Does anyone know the origin of the words $\arccos$, $\arcsin$ & $\arctan$? That is to say, why are they named like this? What connects "arc" with inverse?

Apr 13, 2021 · Hence, it is thus easy to see that $$\theta=\arcsin x=\arg (ix+\sqrt {1-x^2})$$ Similar reasoning applies to your observation about $\arctan x$. Point 2 The regular …

Jan 23, 2018 · What is $\arcsin (a+b)$ in terms of $\arcsin (a)$ and $\arcsin (b)$? Ask Question Asked 7 years, 7 months ago Modified 7 years, 7 months ago

Jan 15, 2017 · There are lots of different angles that all have the same sine. By definition, $\arcsin (x)$ is an angle between $-90$ ° and $90$ ° (or, if you prefer, between $-\pi/2$ and $\pi/2$ …
