A ও B সূক্ষ্মকোণ, $\sin{A} = \frac{1}{2}$   এবং $\cos{B} = \frac{1}{\sqrt{3}}$   হলে tanAtanB এর মান-

$\begin{aligned} \sin A & =\frac{1}{2}, \quad \tan A=\frac{1}{\sqrt{3}} \\ \cos B & =\frac{1}{\sqrt{3}} \quad \tan B=\sqrt{2} \\ \tan A. & \tan B=\frac{1}{\sqrt{3}} \cdot \sqrt{2} \\ & =\frac{\sqrt{2}}{\sqrt{3}}\end{aligned}$
