Question

Arcsin(sin(3pi))

Answer 1

sin^-1(sin(x))=x

Answer 2

not quite...
0

Answer 3

the range of arcsin is -pi/2 to pi/2

Answer 4

well my calculator says 3 pi @dpaInc :P

and yeah sin^-1 (sin x ) = x

sin (sin^-1 x) = x

IF they exist

Answer 5

@lgbasallote , hmm where did you buy your calculator?

Answer 6

and how do you make a yellow post like that to single me out?

Answer 7

technically there are infinite solutions
--> Arcsin(0) = 0+n*pi

Answer 8

but doesn't the capital A in Arcsin mean principal value?

Answer 9

0, pi, 2pi, 3pi, 4 pi, etc are all right

Answer 10

crap...details, details...probably i skipped that lesson on principal values

Answer 11

but i assume their lesson is to prove the thing i said so 3pi would be the answeer

Answer 12

\[\sin^{-1}(\sin( 3pi) = \sin^{-1}(\sin 180)= 0\]

Answer 13

diplomacy....Let's agree to disagree.. :)

Answer 14

nah... now that no one's around...
