There are 1 questions in this calculation: for each question, the 3 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ third\ derivative\ of\ function\ sin(-2x)\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( sin(-2x)\right)}{dx}\\=&cos(-2x)*-2\\=&-2cos(-2x)\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( -2cos(-2x)\right)}{dx}\\=&-2*-sin(-2x)*-2\\=&-4sin(-2x)\\\\ &\color{blue}{The\ third\ derivative\ of\ function:} \\&\frac{d\left( -4sin(-2x)\right)}{dx}\\=&-4cos(-2x)*-2\\=&8cos(-2x)\\ \end{split}\end{equation} \]
