There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ e^{\frac{-1}{10}t}cos(5t) + ({t}^{2} - \frac{1}{10}{t}^{4})\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = e^{\frac{-1}{10}t}cos(5t) + t^{2} - \frac{1}{10}t^{4}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( e^{\frac{-1}{10}t}cos(5t) + t^{2} - \frac{1}{10}t^{4}\right)}{dx}\\=&e^{\frac{-1}{10}t}*0cos(5t) + e^{\frac{-1}{10}t}*-sin(5t)*0 + 0 + 0\\=&0\\ \end{split}\end{equation} \]
