$$\boldsymbol{\mathrm{u}}=\boldsymbol{\mathrm{e}}^{\boldsymbol{\mathrm{e}}^{\boldsymbol{\mathrm{x}}} } \:\:\:\boldsymbol{\mathrm{du}}=\boldsymbol{\mathrm{e}}^{\boldsymbol{\mathrm{x}}} \boldsymbol{\mathrm{e}}^{\boldsymbol{\mathrm{e}}^{\boldsymbol{\mathrm{x}}} } \boldsymbol{\mathrm{dx}} \\ $$$$\left.\int_{\mathrm{0}} ^{\mathrm{1}} \boldsymbol{\mathrm{e}}^{\boldsymbol{\mathrm{u}}} \boldsymbol{\mathrm{du}}=\boldsymbol{\mathrm{e}}^{\boldsymbol{\mathrm{u}}} \right]_{\mathrm{0}} ^{\mathrm{1}} =\left(\boldsymbol{\mathrm{e}}^{\boldsymbol{\mathrm{e}}^{\boldsymbol{\mathrm{e}}^{\boldsymbol{\mathrm{x}}} } } −\boldsymbol{\mathrm{e}}^{\boldsymbol{\mathrm{e}}^{\boldsymbol{\mathrm{e}}^{\boldsymbol{\mathrm{x}}} } } \right)=\boldsymbol{\mathrm{e}}^{\boldsymbol{\mathrm{e}}^{\boldsymbol{\mathrm{e}}} } −\boldsymbol{\mathrm{e}}^{\boldsymbol{\mathrm{e}}} \checkmark \\ $$
