(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Calculate arcsin(sin√5).

2. Relevant equations

None.

3. The attempt at a solution

f(1/2) = sin(1/2)

= π / 6

f'(x) = cosx

f'(1/2) = cos(1/2)

= π / 3

y = π / 6 + π / 3(x - 1/2)

= π / 3 x

f(√5) = π / 3 (√5)

= √5π / 3

I tried using linear approximation, but didnt get the correct answer of π - √5
