A little something I'm trying to understand:
So my question is simple - why? Since each cancels the other, it would make sense that arcsin(sin(x)) would always result in x.sin(arcsin(x)) is always x, but
arcsin(sin(x)) is not always x
I'd appreciate any explanation. Thanks!
Hello, yotamoo!
A little something I'm trying to understand:
. . is always

So my question is: why?
I'll illustrate with a specific example.
(a) We have: .

Then: .
Hence: .
We get back our original value of
(b) We have: .
Suppose
Then: .
Hence: .
There is an infinite number of possible values.
We do not get back our original value of
