Question

Evaluate the expression:
arcsin1/2

Answer 1

arcsin(1/2)= π/6 radians

Answer 2

Thanks. Can you show me how you got that?

Answer 3

arcsin(1/2)= π/6 radians
arcsin(1/2)= 5π/6 radians
This is something that should be memorized. sin(π/6 )=1/2
If sin(π/6 )=1/2, arcsin(1/2) = π/6 radians
sin(5π/6) is also 1/2 =
This is 150 degrees
so, arcsin(1/2) is also 5π/6

Answer 4

Ahh okay thanks
