The solution of differential equation $$\frac{{{{\text{d}}^2}{\text{u}}}}{{{\text{d}}{{\text{x}}^2}}} - {\text{K}}\frac{{{\text{du}}}}{{{\text{dx}}}} = 0$$ where K is constant, subjected to boundary conditions u(0) = 0 and u(L) = U is
A solution of the following differential equation is given by $$\frac{{{{\text{d}}^2}{\text{y}}}}{{{\text{d}}{{\text{x}}^2}}} - 5\frac{{{\text{dy}}}}{{{\text{dx}}}} + 6{\text{y}} = 0$$
