$$$\operatorname{atan}{\left(\frac{1}{2} \right)}$$$

$$$\operatorname{atan}{\left(\frac{1}{2} \right)}$$$을(를) 구하시오.

$$$\operatorname{atan}{\left(\frac{1}{2} \right)}\approx 0.463647609000806$$$A

$$$\operatorname{atan}{\left(\frac{1}{2} \right)} = \left(\frac{180 \operatorname{atan}{\left(\frac{1}{2} \right)}}{\pi}\right)^{\circ}\approx 26.565051177077989^{\circ}$$$A
