Verified Solution

Answer & Solution

Correct Answer

(B) \(\cot \mathrm{h} y\)

Step-by-step Solution

Detailed explanation

\(\frac{\sinh (x+y)+\sinh (x-y)}{\cosh (x+y)-\cosh (x-y)}\) is the given expression Apply si \(n h(x+y)=\sin h x \cos h x+\cosh x \sin h y\) Similarly, apply the formula of \(\sinh (x-y), \cosh (x+y) \& \cos h(x-y)\).…
