Note for OP
+solved @user to close the thread when your doubt is solved. Mention the user who helped you solve the doubt. This will be added to their stats.Bro its property of itf
ðŸ˜
Iske tujhe concept aana chiye sin inverse ki domain or cos inverse ki domain
Try using graphs of itf if you have problem in remembering these things
Graphs use kr
or bring it closer to pi/2 (by manipulation as sin(2npi +x) = x and so on)
as for value closer to pi/2
the equation simply be y = x for arcsin sinx
well my question is les say we have sin-1 Theta and theta is not in range
to get it in range do we -pi from theta or do pi -theta
Let's say I have 10 rad
Then I can manipulate it
arcsine(10) = arcsine (3pi +(10 -3pi)
Now you can write it as
-arcsine(10-3pi)
Or arcsine(3pi-10)
You can easily find this out as for this range, as the equation is just y=x
oh wow thx i get it now
