How do you use a calculator to evaluate cos^-1 0.34 in both radians and degree?

${\cos}^{-} 1 \left(0.34\right) = 1.2238 \left(4 \mathrm{dp}\right)$radian.
${\cos}^{-} 1 \left(0.34\right) = 70.1231 \left(4 \mathrm{dp}\right)$degree.
Using "inv" button with radian and degree mode for ${\cos}^{-} 1$ we get,
${\cos}^{-} 1 \left(0.34\right) = 1.2238 \left(4 \mathrm{dp}\right)$radian.
${\cos}^{-} 1 \left(0.34\right) = 70.1231 \left(4 \mathrm{dp}\right)$degree.[Ans]
