Problem: Find a uniformly valid leading order approximation to the solution of $\epsilon y'' + \sinh(\pi x)y' - y = 0$ with boundary conditions $y(1) = 1; y(2) = 1$ in the limit $\epsilon \to 0^+$. 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: $\boxed{y(x)=(\frac{\tanh(\frac{\pi x}{2})}{\tanh(\pi)})^{\frac{1}{\pi}} + (1 - (\frac{\tanh(\frac{\pi}{2})}{\tanh(\pi)})^{\frac{1}{\pi}}) \exp(\frac{\sinh(\pi)(1-x)}{\epsilon})}$
