There are 1 questions in this calculation: for each question, the 2 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ second\ derivative\ of\ function\ 150sin(\frac{3.14x}{1000})\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 150sin(0.00314x)\right)}{dx}\\=&150cos(0.00314x)*0.00314\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( 0.471cos(0.00314x)\right)}{dx}\\=&0.471*-sin(0.00314x)*0.00314\\ \end{split}\end{equation} \]
