Question

which is equivalent to sin^-1(.75)

Answer 1

Answer: 0.85 radians

Step-by-step explanation:

We have the following trigonometric expression:

$sin^{-1}(0.75)=arcsin(0.75)$

The result of this calculation is:

$sin^{-1}(0.75)=48.59\°$ where the angle is in degrees

If $360\°=2\pi rad$ then:

$48.59\°(\frac{2\pi rad}{360\°}=0.848 rad \approx 0.85 rad$  

Therefore the answer is 0.85 radians
