I do have a suggestion, actually! Here is the original equation:

 

\(2\tan^{-1}{x}=1\) Divide 2 on both sides
\(\tan^{-1}{x}=\frac{1}{2}\)  
\(\tan({\frac{1}{2}})=x\) Evaluate with a calculator.
   


Now, I am giving you 2 answers because I do not know if you want your answer in degree mode or in radian:

 

Degree mode:
\(x\approx0.008726867791 \)

 

Radian mode:
\(x\approx0.546302489844\)

Solve for x:
2 tan^(-1)(x) = 1

Divide both sides by 2:
tan^(-1)(x) = 1/2

Take the tangent of both sides:
Answer: | x = tan(1/2)
