Which is equivalent to sin-1(–0. 4)? Round your answer to the nearest hundredth of a radian.

Sagot :

Using the relationship between the degree and radian. Then the equivalent of [tex]\rm sin^{-1} (-0.4)[/tex] is 5.87 radians.

What is an equivalent function?

The equivalent is the functions that are in different forms but are equal to the same value.

Given

The expression is [tex]\rm sin ^{-1}(-0.4)[/tex].

Then the angle will be

[tex]\rm sin^{-1} (-0.4) = -23.58\\\\sin^{-1} (-0.4) = -23.58 + 360\\\\sin^{-1} (-0.4) = 336.42[/tex]

The angle 336.42 is in degrees.

Conversion of degree into radian.

[tex]\begin{aligned}\rm 1 degree &= \dfrac{2\pi}{360}\\\\336.42\rm \ degrees &= \dfrac{\pi}{180}*336.42 \\\\336.42 \rm \ degrees &= 5.87\end{aligned}[/tex]

Thus, The equivalent of [tex]\rm sin^{-1} (-0.4)[/tex] is 5.87 radians.
