If a Value is out of domain how do we subtract or add pi to get in range . Like in this Q 13

Bro its property of itf

😭

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

[pallid arrow]

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

[pallid arrow]

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
