$$$\operatorname{atan}{\left(4 \right)}$$$

求$$$\operatorname{atan}{\left(4 \right)}$$$。

$$$\operatorname{atan}{\left(4 \right)}\approx 1.325817663668032$$$A

$$$\operatorname{atan}{\left(4 \right)} = \left(\frac{180 \operatorname{atan}{\left(4 \right)}}{\pi}\right)^{\circ}\approx 75.963756532073521^{\circ}$$$A
