Chapter 6: Q. 41 (page 381)

Find the exact value of each expression. Do not use a calculator.
$2 \sin \frac{π}{3} - 3 \tan \frac{π}{6}$

Short Answer

Expert verified

The exact value of the given expression is 0.

Step by step solution

Step 1. Given information.

The given expression is:

$2 \sin \frac{π}{3} - 3 \tan \frac{π}{6}$

Step 2. Determine the exact value.

In the trigonometric table $\sin \frac{π}{3} = \frac{\sqrt{3}}{2}$ and $\tan \frac{π}{6} = \frac{1}{\sqrt{3}}$ . Substitute these values in the given expression.

$\begin{array}{rcl} 2 \sin \frac{π}{3} - 3 \tan \frac{π}{6} & = & 2 (\frac{\sqrt{3}}{2}) - 3 (\frac{1}{\sqrt{3}}) \\ = & \sqrt{3} - \sqrt{3} \\ = & 0 \end{array}$

Step 3. Conclusion.

The exact value of the given expression is 0.
