(B) We know that for any real number $a$,the sum of the inverse trigonometric functions is given by the identity: $	an ^{-1} a + \cot ^{-1} a = \frac{\pi}{2}$.Substituting this identity into the given expression:$\cot \left(	an ^{-1} a + \cot ^{-1} aight) = \cot \left(\frac{\pi}{2}ight)$.Since $\cot \left(\frac{\pi}{2}ight) = 0$,the value of the expression is $0$.

Find the value of $\cot \left(\tan ^{-1} a+\cot ^{-1} a\right)$.
