$$$\operatorname{atan}{\left(\frac{4}{3} \right)}$$$

$$$\operatorname{atan}{\left(\frac{4}{3} \right)}$$$을(를) 구하시오.

$$$\operatorname{atan}{\left(\frac{4}{3} \right)}\approx 0.927295218001612$$$A

$$$\operatorname{atan}{\left(\frac{4}{3} \right)} = \left(\frac{180 \operatorname{atan}{\left(\frac{4}{3} \right)}}{\pi}\right)^{\circ}\approx 53.130102354155979^{\circ}$$$A
