Sine hyperbolic
$$\sinh_r^{-1}(x) \cdot \frac{180}{\pi} = \sinh_d^{-1}(x)$$

Example: $$\sinh_d^{-1}(0.75) \approx 39.71440802747728681136215778124 $$

Cosine hyperbolic
$$\cosh_r^{-1}(x) \cdot \frac{180}{\pi} = \cosh_d^{-1}(x)$$

Example: $$\cosh_d^{-1}(0.75) \approx 751.85603876207549021319455979494 $$

Tangent hyperbolic
$$\sinh_r^{-1}(x) \cdot \frac{180}{\pi} = \sinh_d^{-1}(x)$$

Example: $$\tanh_d^{-1}(0.75) \approx 71.972254550406086233234774472826 $$
