$$$\operatorname{asin}{\left(\frac{4}{5} \right)}$$$

求$$$\operatorname{asin}{\left(\frac{4}{5} \right)}$$$。

$$$\operatorname{asin}{\left(\frac{4}{5} \right)}\approx 0.927295218001612$$$A

$$$\operatorname{asin}{\left(\frac{4}{5} \right)} = \left(\frac{180 \operatorname{asin}{\left(\frac{4}{5} \right)}}{\pi}\right)^{\circ}\approx 53.130102354155979^{\circ}$$$A
