$$$\operatorname{atan}{\left(2 \right)}$$$

$$$\operatorname{atan}{\left(2 \right)}$$$을(를) 구하시오.

$$$\operatorname{atan}{\left(2 \right)}\approx 1.107148717794091$$$A

$$$\operatorname{atan}{\left(2 \right)} = \left(\frac{180 \operatorname{atan}{\left(2 \right)}}{\pi}\right)^{\circ}\approx 63.434948822922011^{\circ}$$$A
