What is the value of arcsin(−1/2) in degrees?

Answer 1

Answer:

-$\frac{\pi }{6}$

Step-by-step explanation:

arcsin(−1/2) = -arcsin(1/2)

In the table of common values,

-arcsin of 1/2 = π/6 = -π/6

Note: Memorize the results of the common values.

Answer 2

Answer: 330°

Step-by-step explanation:

arcsin means sin^-1

So, arcsin(−1/2) is sin^-1(−1/2).

Now,

Let y = sin^-1(−1/2)

y = -30°

If range is between 0° and 360° then,

y = 360° - 30°

y = 330°
