sin⁻¹

we used sin⁻¹ to find the angle whose sine is 0.5.

the calculator showed the result of sin⁻¹(√3/2) was π/3.

to solve for θ, we applied the sin⁻¹ function to both sides.

the range of sin⁻¹ is restricted to [-π/2, π/2] for accurate results.

we need to ensure the argument of sin⁻¹ is within the domain.

the inverse sine, or sin⁻¹, is a trigonometric function.

using sin⁻¹ on -1 gives us an angle of -π/2.

the problem required finding the angle whose sine was 1/2 using sin⁻¹.

we can find the reference angle using sin⁻¹ and the quadrant.

the sin⁻¹ of 0 is 0 radians.

the value of sin⁻¹(0.866) is approximately π/3.
