Find the value of `2cos^(-1)(3/(sqrt(13)))+cot^(-1)((16)/(63))+1/2cos^(-1)(7/(25))`

Explanation

To solve the expression

\[ 2 \cos^{-1} \left( \frac{3}{\sqrt{13}} \right) + \cot^{-1} \left( \frac{16}{63} \right) + \frac{1}{2} \cos^{-1} \left( \frac{7}{25} \right), \]

we will convert the inverse cosine and cotangent functions into inverse tangent functions and simplify the expression step by step.
