Step 1.1

Rewrite $\sec (\frac{π}{3}) \cos (\frac{π}{3})$ in terms of sines and cosines.

$\frac{1}{\cos (\frac{π}{3})} \cos (\frac{π}{3}) - \tan (\frac{π}{6})$

Step 1.2

Cancel the common factors.

$1 - \tan (\frac{π}{6})$

Step 2

The exact value of $\tan (\frac{π}{6})$ is $\frac{\sqrt{3}}{3}$ .

$1 - \frac{\sqrt{3}}{3}$

Step 3

The result can be shown in multiple forms.

Exact Form:

$1 - \frac{\sqrt{3}}{3}$

Decimal Form:

$0.42264973 \dots$
