Question

What is the approximate value of arcsin(0.58).

Answer 1

   
$\displaystyle \\ \arcsin(0.58) \approx \arcsin(0.5) = \arcsin \Big( \frac{1}{2} \Big)= 30^o \\ \\ \Longrightarrow ~~\arcsin(0.58) \approx \boxed{30^o} \\ \\ \texttt{Verification:} \\ \\ \sin(30^o)= \frac{1}{2} = 0.5 \approx 0.58$
