Problem: Find a uniformly valid approximation to the solution of $\epsilon y''(x) + \cosh(x)\,y'(x) - y(x) = 0$ with boundary conditions $y(0)=1, y(1)=1$ in the limit $\epsilon \ll 1$. Use only the variables and constants given in the problem; do not define additional constants. Place your final solution in a $\boxed{}$ LaTeX environment.
Solution: $\boxed{y(x) = \exp (2[\arctan(e^x) - \arctan(e)]) + (1 - \exp (2[\arctan(1) - \arctan(e)]))e^{-\frac{x}{\epsilon}}}$
