Wrapping text

[hfactorcode]

I have a latex code something like this

\text{Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy te}

\begin{array}{l}
\text { Let } f(x, y)=x^{y}+y^{x} \
\text { Then, } \frac{\partial f}{\partial x}=y x^{y-1}+y^{x} \log _{e} y ; \text { Similarly }, \frac{\partial f}{\partial y}=x^{y} \log _{e} x+x y^{x-1} \
\therefore \quad \frac{d y}{d x}=-\frac{\partial f / \partial x}{\partial f / \partial y}=-\frac{y^{x} \log _{e} y+y^{y-1}}{x^{y} \log _{e} x+x y^{x-1}}
\end{array}

Is there a way to break the text
