There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 340t - 2e^{-2(t - \frac{1}{5})}sin(14pi(t - \frac{1}{5}))\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 340t - 2e^{-2t + \frac{2}{5}}sin(14tpi - \frac{14}{5}pi)\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 340t - 2e^{-2t + \frac{2}{5}}sin(14tpi - \frac{14}{5}pi)\right)}{dx}\\=&0 - 2e^{-2t + \frac{2}{5}}(0 + 0)sin(14tpi - \frac{14}{5}pi) - 2e^{-2t + \frac{2}{5}}cos(14tpi - \frac{14}{5}pi)(0 + 0)\\=& - 0\\ \end{split}\end{equation} \]
