TeX (original user input):
\frac{dL}{dt}=\sum\limits_{k}^{{}}{\left( \frac{\partial L}{\partial {{{\dot{q}}}_{k}}}{{{\ddot{q}}}_{k}}+\frac{d}{dt}\frac{\partial L}{\partial {{{\dot{q}}}_{k}}}{{{\dot{q}}}_{k}} \right)}=\frac{d}{dt}\sum\limits_{k}^{{}}{\frac{\partial L}{\partial {{{\dot{q}}}_{k}}}{{{\dot{q}}}_{k}}=2\frac{dT}{dt}}
TeX (checked):
{\frac {dL}{dt}}=\sum \limits _{k}^{}{\left({\frac {\partial L}{\partial {{\dot {q}}_{k}}}}{{\ddot {q}}_{k}}+{\frac {d}{dt}}{\frac {\partial L}{\partial {{\dot {q}}_{k}}}}{{\dot {q}}_{k}}\right)}={\frac {d}{dt}}\sum \limits _{k}^{}{{\frac {\partial L}{\partial {{\dot {q}}_{k}}}}{{\dot {q}}_{k}}=2{\frac {dT}{dt}}}
