&#12304;General guidance&#12305;The answer provided below has been developed in a clear step by step manner.Step1/2We find equation of the tangent line and normalization of the curve at the given pointExplanation:Please refer to solution in this step.Step2/2Given $$\mathrm{{y}^{{3}}{\cosh{{x}}}={e}^{{y}}+{x}}$$Differentiate with respect to $$\mathrm{'{x}',}$$ We get\begin{align*} \mathrm{\frac{{d}}{{\left.{d}{x}\right.}}{\left[{y}^{{3}}{\cosh{{x}}}\right]}} &= \mathrm{\frac{{d}}{{\left.{d}{x}\right.}}{\left[{e}^{{y}}+{x}\right]}}\\[3pt]\mathrm{\Rightarrow{3}{y}^{{2}}{\cosh{{x}}}.\frac{{\left.{d}{y}\right.}}{{\left.{d}{x}\right.}}+{y}^{{3}}{\sinh{{x}}}} &= \mathrm{{e}^{{y}}.\frac{{\left.{d}{y}\right.}}{{\left.{d}{x}\right.}}+{1}}\\[3pt]\mathrm{\Rightarrow{\left({3}{y}^{{2}}{\cosh{{x}}}-{e}^{{y}}\right)}\frac{{\left.{d}{y}\right.}}{{\left.{d}{x}\right.}}} &= \mathrm{{1}-{y}^{{3}}{\sinh{{x}}}}\\[3pt]\mathrm{\Rightarrow\frac{{\left.{d}{y}\right.}}{{\left.{d}{x}\right.}}} &= \mathrm{\frac{{{1}-{y}^{{3}}{\sinh{{x}}}}}{{{3}{y}^{{2}}{\cosh{{x}}}-{e}^{{y}}}}\ \text{ }\ \ \text{ }\ \leftarrow{s}{l}{o}{p}{e}} \end{align*}At $$\mathrm{{\left(-{1},{0}\right)}}$$\( \begin{align*} \mathrm{{m}=\frac{{\left.{d}{y}\right.}}{{\left.{d}{x}\right.}}} &= \mathrm{\frac{{{1}-{0}.{\sinh{{\left(-{1}\right)}}}}}{{{ ...
