Question

2 tan 30 degree /1minus tan^2 30 degree is equal to?

Answer 1

Answer:

2 tan 30/1- tan^2 30 degree =2(1/√3) /1-1/3

• =2/√3/2/3= 3/√3 or √3 is ur ans...

Answer 2

Answer:

$\frac{2tan30}{1 - {tan}^{2}30 } \\ = \frac{2 \times \frac{1}{ \sqrt{3} } }{1 - ( { \frac{1}{ \sqrt{3} } }^{2}) } \\ = \frac{ \frac{2}{ \sqrt{3} } }{1 - \frac{1}{3} } \\ = \frac{2}{ \sqrt{3} } \times \frac{3}{2} \\ = \frac{3}{ \sqrt{3} } \\ = \sqrt{3} . \\ answer \: \:$
