Question

solve
$2 \tan(30) \div 1 - \tan^{2} 30$
​

Answer 1

Step-by-step explanation:

$\frac{2 \tan(30) }{1} - { \tan }^{2}(30) \\ = 2( \frac{ \sqrt{3} }{3} ) - {( \frac{1}{ \sqrt{3} } ) }^{2} \\ = \frac{2 \sqrt{3} }{3} - \frac{1}{3} \\ = \frac{2 \sqrt{3 } - 1 }{3}$

NOTE THAT:

tan30° = (√3/3) = (1/√3)
