计算 $2 \sin 30^{\circ}+\tan 30^{\circ} \cdot \cos 30^{\circ}$
计算 $\sqrt{\left(1-\tan 60^{\circ}\right)^2}+\left(2-\cos 45^{\circ}\right)^{\circ}-\frac{1}{\sin 45^{\circ}}$
$2 \cos ^2 30^{\circ}-2 \sin 60^{\circ} \cos 45^{\circ}$
$\sqrt{8}+\tan 45^{\circ}-(\pi-3.14)^{\circ}-4 \cos 45^{\circ}+\left(-\frac{1}{3}\right)^{-1}$
$\tan 30^{\circ} \sin 60^{\circ}-\cos ^2 45^{\circ}+\tan 45^{\circ}$;
$\sqrt{\left(\tan 60^{\circ}-1\right)^2}+\left|1-\cos 60^{\circ}\right|-2 \tan 45^{\circ} g \cos 30^{\circ}$.
$\tan 60^{\circ} \cos 30^{\circ}+\sqrt{2} \sin 45^{\circ}$;
$(\pi-1)^0-\sqrt{9}+\sqrt{3} \sin 30^{\circ}+\left(\frac{1}{5}\right)^{-1}$.
$4 \cos 30^{\circ}-3 \tan 60^{\circ}+2 \sin 45^{\circ} \cdot \cos 45^{\circ}$.
$\sqrt{24}-3 \sqrt{2} \tan 30^{\circ}+|3-\pi|-\left(-\frac{1}{3}\right)^{-1}$.
